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.

After witnessing some strange errors with memory not being
what it should be, lifiting everything above 1MB has solved
it. The Zephyr binary was being loaded into memory containing
reserved regions, resulting in data corruption.
We still simulate XIP for testing purposes by setting up the
memory map as follows:
0x000000 - 0x0FFFFF : Non-present
0x100000 - 0x4FFFFF : "Flash" ROM region
0x500000 - 0x8FFFFF : "SRAM" RAM region
For a total of 9 megabytes of physical RAM used.
Fixes problems observed in some large tests when code coverage
is enabled (which increases the amount of RAM used even more).

The DT spec. only has "okay" and not "ok". The Linux kernel has around

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

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.
Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
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 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.

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.
