Removes very complex boot-time generation of page tables
with a much simpler runtime generation of them at bootup.
For those x86 boards that enable the MMU in the defconfig,
set the number of page pool pages appropriately.
The MMU_RUNTIME_* flags have been removed. They were an
artifact of the old page table generation and did not
correspond to any hardware state.

Qemu_x86 didn't reflect emulated program memory size.
It was because chosen zephyr,flash was assigned to flash_simulator
which was helping to generate DT_FLASH properties for sim_flash node.
This change revert choice of flash0 which solve problem with
program memory size. Flash simulator have to use
DT_SOC_NV_FLASH_xxx labels for fetch its property since that.

The desired memory map is to have the 0 - 4K page non-present
to catch NULL pointer dereferences,
from 4K - 4MB for the program text (RO, Execute),
ROM (RO, No Execute), and 4MB-8MB for system RAM.
This patch cut text size by 4 KB which allow to meet above
requirements.

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"/'

This helps by letting us add checks for when the runner has already
been set. There is documentation saying you can set
-DBOARD_DEBUG_RUNNER at the command line and have it take effect,
which turns out not to be true for a large number of boards.
A status message helps the user debug.

The '#if XIP' in the DTS file never worked properly,
causing the QEMU build to think it has much more RAM
then it actually has. If RAM overflowed, this would not
be caught by the build, instead there would be strange
crashes when the data copy takes place.
The QEMU targets themselves are not XIP, everything
is actually RAM, but the first 4 megabytes are
considered to be a memory-mapped flash region. This
is done to ensure that the XIP data copying infrastructure
doesn't bit-rot on x86. We are at the point where
a lot of things depend on this, so just select it in
the board Kconfig instead of enabling in the
defconfigs.

This build target is intended to verify that enabling the
IAMCU ABI doesn't have any bit-rot since we can easily
run this under emulation.
However, the QEMU boards all derive from the generic IA32
SOC definition, which is any pc-like hardware. We need
to disable these mitigations for this target since the
IAMCU compiler doesn't even recognize instructions like
'lfence'.

Not all boards can get the coverage reports. The report generation
needs minimum of 64KB SRAM. This patch added support for mps2_an385,
qemu_cortex_m3, qemu_x86. This is just a subset. Also the previously
supported board native_posix is included in this patch.
If a board has 64KB RAM, it can generate reports by just
adding HAS_COVERAGE_SUPPORT in Kconfig.board.

"-machine type=pc-0.14" appears to be the option which leads to
broken PCI emulation in QEMU, where PCI enumeration reports one
IRQ number (11), while actually IRQ 10 is emulated by QEMU.
"-vga none" and "-display none" appear to be just subordinate of
"-machine type=pc-0.14" and are required to get qemu_x86 into
bootable state.

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c
