A parallel PCI implementation ("pcie") is added with features for PCIe.
In particular, message-signaled interrupts (MSI) are supported, which
are essential to the use of any non-trivial PCIe device.
The NS16550 UART driver is modified to use pcie.
pcie is a complete replacement for the old PCI support ("pci"). It is
smaller, by an order of magnitude, and cleaner. Both pci and pcie can
(and do) coexist in the same builds, but the intent is to rework any
existing drivers that depend on pci and ultimately remove pci entirely.
This patch is large, but things in mirror are smaller than they appear.
Most of the modified files are configuration-related, and are changed
only slightly to accommodate the modified UART driver.
Deficiencies:
64-bit support is minimal. The code works fine with 64-bit capable
devices, but will not cooperate with MMIO regions (or MSI targets) that
have high bits set. This is not needed on any current boards, and is
unlikely to be needed in the future. Only superficial changes would
be required if we change our minds.
The method specifying PCI endpoints in devicetree is somewhat kludgey.
The "right" way would be to hang PCI devices off a topological tree;
while this would be more aesthetically pleasing, I don't think it's
worth the effort, given our non-standard use of devicetree.

One of these is from 'source'ing a file within an 'if SERIAL', and then
adding another 'depends on SERIAL' within it.
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

This effectively reverts part of earlier 49bb163756 which moved
interrupt acknowledgement until after return from the user callback.
This was done confusing the flow of this driver with how some other
drivers do it, where pending interrupt status is checked by
uart_irq_rx_ready()/uart_irq_tx_ready(), which should be called by
the callback. But the uart_cmsdk_apb driver actually uses different
hardware register in these functions. And acking IRQs after user
callback can lead to race condition and losing an IRQ, and the
simple fix in this case is just move acknowledgement to where it

The Zephyr console and shell interrupt processing assumes
a TX interrupt is evoked upon first enabling the TX
interrupt via uart_irq_tx_enable.
This was not the case with the cc32xx uart, coming out of
reset, with FIFO's disabled.
The only way found to achieve this behavior is to fill
the fifo with a non-printable character on initialization.
Also, the uart driver was explicitly clearing TX/RX interrupts in
its isr, which was unnecessary, as the act of reading/writing
did that implicitly.
These fixes allow the cc32xx uart to work with the
current Zephyr console/shell design.

1. There's an expectations that TX ready (i.e. TX buffer space
available) interrupt is a level interrupt, i.e. always active
while there's TX buffer space available. In particular, there's
an expectation that after uart_irq_tx_enable(), the TX interrupt
will immediately fire (assuming free TX buffer space is available).
But CMSDK UART interrupt appears to be edge interrupt, firing only
on buffer state change. So, after irq_tx_enable(), we need to
"bootstrap" interrupt processing by calling user-defined ISR
manually (the ISR will see that TX ready to accept a new char,
will write it there, then we'll get interrupt once TX buffer is
ready again).
2. Interrupts should be acknowledges only after user ISR is called,
because the ISR will check the status of interrupts.

Zephyr UART drivers offer very low-level functionality. Oftentimes,
it would be useful to provide higher-level wrappers around UART
device which would offer additional functionality. However, UART
driver irq callback routine receives just a pointer to (low-level)
UART device, and it's not possible to get to a wrapper structure
(without introducing expensive external mapping structures). This
is an indirect reason why the current UARt wrappers - uart_pipe,
console - are instantiated statically just for one underlying UART
device and cannot be reused for multiple devices.
Solve this by allowing to pass an arbitrary user data to irq
callback, set by new uart_irq_callback_user_data_set() function.
Existing uart_irq_callback_set() keeps setting a callback which
will receive pointer to the device.
While public API maintains compatibility, drivers themselves need
to be updated to support arbitrary user data storage/passing (as
legacy uart_irq_callback_set() functionality is now implemented in
terms of it).

- Remove redundant 'n' defaults. 'n' is the default value for bool
symbols.
This makes the auto-generated documentation clearer as well: You get
"implicitly defaults to n" instead of
"- n if <propagated dependencies>".
- Shorten
<type>
prompt "foo"
to
<type> "foo"
This works for all types, not just bool.
- Various formatting nits.

This patch changes the way the transmitter is handled in the UART
driver, so that it is activated only when there is something to send.
The current UART API does not allow to disable RX completely, since
the poll_in function description implies that UART must continuously
listen. To provide a way of disabling the entire UART and lowering the
current consumption, this patch adds the power management to the UART
driver. When instructed to enter any of the power saving states,
the driver will disable the UART, and it will enable the UART back
when it is switched again to the active state.

This extends the NS16550 driver to support 4 ports.
Also, this adds the necessary bits to enable PCI enumeration
on port 2.

The CONFIG_UART_NS16550_PORT_1_PCI was accidentally removed in
commit 26b474c987. So adds it back.
This allows PCI driver to probe the resources for port 1.

In nsim, 'nsim_mem-dev=uart0,base=0xf0000000,irq=24'
is used to enable a virtual uart.
This uart is only used to output now, so only poll output
is implemented.
If required, input and interrupt driven are possible.

The dependency on the GPIO driver was a bit artificial, since the UART
driver used the GPIO API functions only to configure the pins at its
initialization. This configuration will be done by using nrfx GPIO HAL
functions directly, just like in case when a shim is using
an nrfx driver underneath.
HAL functions can be fed with the absolute pin numbers, that are
currently used for Nordic SoCs in Kconfig and DT, and for the GPIO
driver an additional translation would be required, to extract
the port and its relative pin number.
UART driver has to be initialized at PRE_KERNEL_1 (because of the
console using it) and currently the GPIO driver is initialized
at POST_KERNEL stage, so calling its API function form the UART
initialization routine was incorrect.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.
This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

1. API function: uart_nrfx_irq_tx_enable is expected to enable and
trigger TXDRDY interrupt. Due to HW limiation before first byte has
been sent TXDRDY interrupt will not be triggered so it must be forced
by the software.
2. Common function: uart_nrfx_irq_tx_ready_complete is used for two
API entries: irq_tx_ready, irq_tx_complete because Nordic hardware does
not distinguish between them. This function returns 1 when driver is
ready to accept data and 0 otherwise.
3. Removed Hungarian prefixes.
