soc/amd/mendocino: Populate type 0x63 entry with right MRC Cache

On boards with RECOVERY_MRC_CACHE FMAP section, populate type 0x63 BIOS
directory entry in RO with that section. If the RECOVERY_MRC_CACHE
section is not present, then fall back to RW_MRC_CACHE.

BUG=b:270569389
TEST=Build and boot to OS in Skyrim. Ensure that the Type 0x63 BIOS
directory entry is populated with the base and size of appropriate MRC
cache.
