soc/amd/stoneyridge: Load SMU fimware using PSP
Add the ability to locate the SMRAM-based SMU firmware early and
call the PSP library to load it prior to DRAM initialization. This
is currently placed in bootblock to ensure the blob is loaded
before any reset occurs.
Add similar functionality in ramstage for SMU FW2 to the hook already
in place for running AmdInitEnv. Rename the hook to make more sense.
This patch was tested using a pre-released PSP bootloader on a
google/kahlee system.
Leave the option unused until the bootloader is ready.
