soc/amd/phoenix: Add SVC call to inject v2 hash tables
On mainboards using Phoenix SoC with PSP verstage enabled, to
accommodate growing number of PSP binaries, multiple smaller hash tables
are introduced. Also some hash tables are in V2 format identifying the
concerned PSP binaries using UUID. Add SVC calls to support multiple
hash tables with different versions.
BUG=b:277292697
TEST=Build and boot to OS in Myst with PSP verstage enabled. Ensure that
all the hash tables are injected successfully. Ensure that PSP validated
all the signed PSP binaries using the injected hash tables successfully.
