In order to bring consistency in-tree, migrate all soc code to the
new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

Add MPU REGION_FLASH_SIZE definitions for 128M-512M flash sizes, to handle
arm SOCs with large flash regions.

Currently the only way for a BOARD/SOC to configure at compile time the
MPU regions is to add, in a soc-specific file, the 'mpu_config' struct
adding static entries for the new regions with the needed attributes
(cacheable, non-cacheable, etc...). This exported struct is then read by
the MPU driver at boot time and used to properly setup the MPU regions.
At the same time it is now possible to introduce new memory regions in
the DT using the newly introduced 'zephyr,memory-region' attribute.
What is missing is the link between these two solutions: that is how to
declare the memory regions in the DT and automatically configure these
regions in the MPU with the correct attributes.
This patch is trying to address exactly this problem.
It is now possible to declare the memory regions in the DT and define
the MPU attributes for the regions using the 'zephyr,memory-region-mpu'
property. When this new property is present together with the
'zephyr,memory-region' property and a the 'zephyr,memory-region'
compatible, the 'mpu_config' struct is automatically extended at
compile-time to host the DT defined regions with the correct MPU
attributes.
So for example in the DT we can now have:
sram_cache: memory@20200000 {
compatible = "zephyr,memory-region", "mmio-sram";
reg = <0x20200000 0x100000>;
zephyr,memory-region = "SRAM_CACHE";
zephyr,memory-region-mpu = "RAM";
};
and a new region will be created called "SRAM_CACHE" and a new MPU
region will be configure at boot time with the attribute
"REGION_RAM_ATTR".

Added support for 8 MB MPU regions for SRAM sizes between 4 and 8 MB,
and 16 MB MPU regions for SRAM sizes between 8 and 16 MB.

1. Added RT10xx and RT11xx configs
2. Added a new soc file for rt117x. There are clock differences
between the RT10xx and RT11xx series, hence the soc files
have been separated.

Before introducing the code for ARM64 (AArch64) we need to relocate the
current ARM code to a new AArch32 sub-directory. For now we can assume
that no code is shared between ARM and ARM64.
There are no functional changes. The code is moved to the new location
and the file paths are fixed to reflect this change.

We move the configuration of the fixed MPU regions for ARM
Cortex-M SoCs in a common place under soc/arm/common/cortex-m,
instead of having this configuration present in each ARM SoC or
SoC Series definition. The rationale behind this is that for all
SoCs the fixed MPU regions configured at SoC definition are only
used for enforcing default Flash and SRAM access policies, and
currently, this is common to all ARM SoCs with MPU support.
We also simplify the Flash and SRAM MPU region definition,
aiming at using a single MPU region index to program each
of them.
We still support the possibility for ARM SoCs to opt-out and,
instead, define their own custom fixed MPU regions at SoC
definition. We do it using a Kconfig option, introduced
explicitly for this purpose.
