soc/amd/mendocino: Add support for separate RW A/B partition SPL file
Add support for having different Security Patch Level (SPL) table files
in the read-only and the read-write A/B partitions. This allows the SPL
table file in the main or RO FMAP partition to only cover the embedded
firmware binaries in that partition and have a separate SPL file in the
RW A and B partitions that covers the embedded firmware binaries in the
RW partitions.
