794656913b include: arm64: Add BSS align when MPU enabled
When MPU is enabled, the sections need to be 64 bytes aligned.
In the case of MMU, BSS section will be 4k aligned, because the first
variable in BSS section 'base_xlat_table' is explicitly aligned by
'__aligned(NUM_BASE_LEVEL_ENTRIES * sizeof(uint64_t))'.

However, with MPU, we do not have such a variable. So it's necessary
to fix the alignment of the BSS section in the linker.ld

3539c2fbb3 arm/arm64: Make ARM64 a standalone architecture
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
