This driver was still using CONFIG_* values to determine its address,
IRQ, etc. Add a binding for an "intel,hpet" device and migrate this
driver to devicetree.

XIP support in x86 was something of a mess. This
patch does the following:
- Generic ia32 SOC no longer defines a "flash" region
as generic X86 devices don't have a microcontroller-
like concept of flash. The same has been done for apollo_lake.
- Generic ia32 and apollo_lake SOCs starts memory at 1MB.
- Generic ia32 SOC may optionally have CONFIG_XIP enabled.
The board definition must provide a flash region definition
that gets exposed as DT_PHYS_LOAD_ADDR.
- Fixed definitions for RAM/ROM source addresses in ia32's
linker.ld when XIP is turned off.
- Support for enabling XIP on apollo_lake SOC removed, there's
no use-case.
- acrn and gpmrb boards have flash and XIP related definitions
removed.
- qemu_x86 has a fake flash region added, immediately after system
RAM, for use when XIP is enabled. This used to be in the ia32 SOC.
However, the default for qemu_x86 is to now have XIP disabled.
- Fixed tests/kernel/xip to run by default on boards that enable
XIP by default, plus an additional test to exercise XIP on
qemu_x86 (which supports it but has XIP switched off by default)
The overall effect of this patch is to:
- Remove XIP configuration for SOC/boards where it does not make
any sense to have it
- Support testing XIP on qemu_x86 via tests/kernel/xip, but leave
it off by default for other tests, to ensure it doesn't bit-rot
and that the system works in both scenarios.
- XIP remains an available feature for boards that need it.

The DT spec. only has "okay" and not "ok". The Linux kernel has around
12k "okay"s and 300 "ok"s.
The scripts/dts scripts only check for "disabled", so should be safe re.
those at least.
The replacement was done with
git ls-files | xargs sed -i 's/status\s*=\s*"ok"/status = "okay"/'

Since Kconfig is responsible for enabling/disabling devices at build,
the devices in dt are defaulted to status="ok" to keep the output in
generated_dts_board.conf the same across configurations and simplify
the board-level dts files.

Previous the register size was 1M, technically the there are only a
small handful of registers defined in the IOAPIC, so shrinking the size
to 4k, so its as most one page large.

The IOAPIC node shouldn't have been in the cpu container, especially
since the cpu container does:
#address-cells = <1>;
#size-cells = <0>;
So the reg field of the IOAPIC would be treated as 2 registers instead
of a register and size. Move IOAPIC node out of the CPU node fixes this
issue.

The Apollo Lake devicetree is augmented with its 8 I2C interfaces.
The default number of dynamic IRQ stubs is increased to deal with
these new interfaces having IRQ vector detection at runtime.

The UARTs are on the SoC, not the board, so move their descriptors
to the SoC-level. Also turn on auto IRQ detection as these are PCI-
attached and their IRQs are subject to change depending upon firmware
settings.

The GPIO driver for the Intel Apollo Lake has so many pins it has to
export ten devices to shoehorn its one device into the GPIO API. The
current implementation uses the shared IRQ driver because these
pseudodevices all share one IRQ. However, since the GPIO driver is
aware of all the possible interrupt sources, it's smaller and faster
(and not even messy) to handle it internally, so this patch eliminates
the dependency on the shared IRQ driver.

To avoid confusion, callbacks using ordinal pin numbers
is going to be reverted. So the driver has to be re-worked
to expose multiple devices so each device has 32 pins.

Now that we have a common DT_SIZE_K macro use it instead of defining
__SIZE_K eveywhere. We also have DT_SIZE_M, so use that in a few
places as well.

This adds the SoC configuration for Apollo Lake. This is based
on the Atom configuration.
