The PR removes the exclusive limit on enabling both UART_ASYNC_API
and UART_INTERRUPT_DRIVEN so that both options can be enabled
together for same uart driver.
Also, the interrupt handler will be used for both cases. So, enable
definition of interrupt handler for both.
However, nRF UART driver still wants to enable only one of them.
So, a new config is added to disable the code for UART_ASYNC_API
when the option UART_INTERRUPT_DRIVEN is enabled.

A new function pcie_irq_enable() is added to be used in lieu of
irq_enable() when the target device is PCI(e)-attached. The function
attempts to use MSI, when configured in the kernel and supported by
the endpoint; failing that, it will verify that IRQ requested is in
fact routed to the device by the boot firmware before enabling it.
The NS16550 UART driver is updated to use pcie_irq_enable().
The PCI(e) shell is extended to dump information about wired IRQs.
The up_squared devicetree is fixed (reverted?) to IRQ5 for UART1.
The galileo enables MSI by default.

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.

The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.
To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.
This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

Update reserved function names starting with one underscore, replacing
them as follows:
'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.
Various generator scripts have also been updated as well as perf,
linker and usb files. These are
drivers/serial/uart_handlers.c
include/linker/kobject-text.ld
kernel/include/syscall_handler.h
scripts/gen_kobject_list.py
scripts/gen_syscall_header.py

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.

The UARTs on the Apollo Lake SoCs have PLLs that feed the baud rate
generators. This patch allows a user to specify custom M/N values for
those PLLs when custom/high-speed baud rates are required.
I'm not entirely satisfied with the way the PCP values are configured,
because it requires tweaking data in both Kconfig and DeviceTree. For
the time being I've merely taken my cue from another similar feature
(the DLF register support) and have punted on figuring out the "right
way" to expose UART configuration to the application.
