soc/amd/mendocino: PSP_INCLUDES_HSP

Select HSP config to indicate that the SoC includes Hardware Security
Processor. This will allow PSP verstage to get and report the HSP state.

BUG=None
TEST=Build Skyrim BIOS image and boot to ChromeOS on Skyrim.  Verify
that HSP is reported during the boot sequence.
