vc/amd,soc/amd/mendocino: Add SVC_CMD_GET_PREV_BOOT_STATUS
Add an SVC command to get the previous boot status. If there is any
pre-x86 boot failure in the previous boot cycle, PSP stores it in warm
reset persistent register and triggers a warm reset. PSP verstage on the
subsequent boot gets the previous boot status and reports any failure to
the vboot before a FW slot is selected.
BUG=b:242825052
TEST=Build Skyrim BIOS image and boot to OS in Skyrim. Trigger a failure
scenario by corrupting certain firmware blobs and observe that PSP
reports the failure boot status. On a normal boot, observed that PSP
reports successful boot.
