soc/amd/common/psp_verstage: Support multiple hash tables

Currently PSP verstage updates PSP bootloader with one unified hash
table containing hashes for all the signed PSP binaries to be validated.
With growing number of PSP binaries to validate and memory constraints
in PSP, there is a requirement to split and update the hash table into
multiple smaller chunks. Hence change the update_psp_fw_hash_table()
signature such that the hash tables are updated in a chipset specific
way.

BUG=b:277292697
TEST=Build and boot to OS in Myst with PSP verstage enabled. Build the
Skyrim BIOS image and confirm that the hash table is identical before
and after this change.
