refactor(morello): update SDS driver calls

Update SDS driver calls to align with recent
changes [1] of the SDS driver.

- The driver now requires us to explicitly pass
  the SDS region id to act on.
- Implement plat_sds_get_regions() platform function
  which is used by the driver to get SDS region
  information per platform.
