When userspace enabled, the zephyr data region should start from
_app_smem_start instead of __kernel_ram_start.

This patch mainly moves mpu related code from
arch/arm64/core/cortex_r/mpu/ to arch/arm64/core/cortex_r/ and moves
the mpu header files from include/arch/arm64/cortex_r/mpu/ to
include/arch/arm64/cortex_r/

Cleanup and preparation commit for linker script generator.
Zephyr linker scripts provides start and end symbols for each larger
areas in the linker script.
The symbols _image_text_start and _image_text_end sometimes includes
linker/kobject-text.ld. This mean there must be both the regular
__text_start and __text_end symbols for the pure text section, as well
as <group>_start and <group>_end symbols.
The symbols describing the text region which covers more than just the
text section itself will thus be changed to:
_image_text_start -> __text_region_start
_image_text_end -> __text_region_end

Cleanup and preparation commit for linker script generator.
Zephyr linker scripts provides start and end symbols for each larger
areas in the linker script.
The symbols _image_rom_start and _image_rom_end corresponds to the group
ROMABLE_REGION defined in the ld linker scripts.
The symbols _image_rodata_start and _image_rodata_end is not placed as
independent group but covers common-rom.ld, thread-local-storage.ld,
kobject-rom.ld and snippets-rodata.ld.
This commit align those names and prepares for generation of groups in
linker scripts.
The symbols describing the ROMABLE_REGION will be renamed to:
_image_rom_start -> __rom_region_start
_image_rom_end -> __rom_region_end
The rodata will also use the group symbol notation as:
_image_rodata_start -> __rodata_region_start
_image_rodata_end -> __rodata_region_end

With this patch, zephyr can enable SMP directly. Otherwise
zephyr needs TB-R to provide psci function.

Add strong definition z_arm64_el2_plat_init() and it is controlled
by CONFIG_SOC_FVP_AEMV8R_EL2_INIT.
VMPIDR_EL2 must be set manually on EL2. The purpose of VMPIDR_EL2 is
that holds the value of the Virtualization Multiprocessor ID and This
is the value returned by EL1 reads of MPIDR_EL1

Add support for the FVP Base RevC 2xAEMv8A board to be emulated using
the same FVP. For now the virtual platform is only exposing one core and
the basic set of peripherals (GICv3, ARM arch timer, PL011, etc...).

Split ARM and ARM64 architectures.
Details:
- CONFIG_ARM64 is decoupled from CONFIG_ARM (not a subset anymore)
- Arch and include AArch64 files are in a dedicated directory
(arch/arm64 and include/arch/arm64)
- AArch64 boards and SoC are moved to soc/arm64 and boards/arm64
- AArch64-specific DTS files are moved to dts/arm64
- The A72 support for the bcm_vk/viper board is moved in the
boards/bcm_vk/viper directory
