Add a new selectable Kconfig option to decide wether the device driver
is a MMIO device or not. Previous to this patch, the decision was maded
based on the existence of a definition in <soc.h>. The design was
fragile, as code compiled anyway if the definition was not present.
All platforms/boards that had the definition in <soc.h> select the
Kconfig option in their respective defconfig files.

Follow up on commit bfd45e5b8c
("drivers: remove Kconfig option CONFIG_UART_CONSOLE_ON_DEV_NAME")
Remove Kconfig options
CONFIG_BT_UART_ON_DEV_NAME and CONFIG_BT_MONITOR_ON_DEV_NAME
since all UART drivers are converted to devicetree and we can just use
DEVICE_DT_GET(DT_CHOSEN(zephyr_bt_uart)) and
DEVICE_DT_GET(DT_CHOSEN(zephyr_bt_mon_uart)).

There is a choice to log btmon logs over UART or RTT.
You can choose number of RTT buffer, set its name and size.
Replaced CONFIG_BT_DEBUG_MONITOR with CONFIG_BT_DEBUG_MONITOR_UART
for UART usage and CONFIG_BT_DEBUG_MONITOR_RTT for RTT.

We assume that all x86 CPUs do have clflush instructions.
And the cache line size is now provided through DTS.
So detecting clflush instruction as well as the cache line size is no
longer required at runtime and thus removed.

The new APIs are not only dealing with cache flushing. Rename the
Kconfig symbol to CACHE_MANAGEMENT to better reflect this change.

For a while now, we've had two APIC drivers. The older was preserved
initially as the new (much smaller, "new style") code didn't have
support for Quark interrupt handling. But that's long dead now. Just
remove it.
Note that this migrates the one board using this driver (acrn) to
CONFIG_APIC_TIMER instead.

Change to code to use the automatically generated DT_INST_*
defines and remove the now unneeded configs and fixups.

The sole purpose of init options has been to enable hardware flow
control on NS16750 when asked. Use the proper DTS tags for this.

Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.
Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.
Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

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.

This can help find unused symbols. Those end up without a type if
'default' is used instead of 'def_bool', which generates a warning.
Search for "Kconfig.defconfig" in
https://docs.zephyrproject.org/latest/application/kconfig-tips.html for
a longer explanation.
Keep the 'def_bool' for the following symbols, which seem to be
deliberately defined only in Kconfig.defconfig files:
- ALTERA_AVALON_I2C
- ALTERA_AVALON_MSGDMA
- ALTERA_AVALON_PIO
- ALTERA_AVALON_QSPI
- ALTERA_AVALON_SYSID
- CLOCK_CONTROL_IMX_CCM
- CPU_EM4_DMIPS
- CPU_EM4_FPUDA
- CPU_EM4_FPUS
- FP_FPU_DA
- I2C_GECKO
