soc/amd/(common,mendocino)/psp_verstage: Pass PSP FW hash table

Copy AMD PSP fw hash table into memory, then pass it to the PSP.
The PSP will use this hash to verify it's the correct firmware bundled
with coreboot build and not replaced.

BUG=b:203597980
TEST=Build Skyrim BIOS image with the hash table and boot to OS after
PSP verified the binaries against the hash table.
