Isolation L3 for AN521 and Musca-B1
- Add Isolation L3 region configuration for AN521 and Musca-B1.
- Add level3-specific linker script/scatter load files for these
two platforms. The other platforms do not support L3 and do not
need specific load files at current stage.
- Implement level3-specific dynamic MPU region switching function
tfm_hal_mpu_update_partition_boundary() while isolation level3
is chosen.
