refactor(sgi): 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.
