soc/amd/common/block/apob_cache: Add support for RECOVERY_MRC_CACHE
If a mainboard has RECOVERY_MRC_CACHE and the recovery mode is enabled,
then use APOB data from that section and make any updates to that
section. Otherwise continue to use DEFAULT_MRC_CACHE section.

TEST=Build and boot to OS in Skyrim.
When in normal mode, DEFAULT_MRC_CACHE is used.
