vc/amd/*,soc/amd/*: Add SVC call to get HSP Secure State
Add an SVC call to get the state of Hardware Security Processor (HSP) in
AMD SoCs. This SVC call will be used from PSP verstage to get and
report HSP state.
BUG=b:198711349
TEST=Build Skyrim BIOS image and boot to OS. Ensure that the HSP state
is read and reported in the firmware logs.
