soc/amd/common/block/include/amdblocks/psp.h: Replace todo message
It was decided to not add the buffers definitions, so the todo message
is obsolete. Replace it with minimum instructions about when a new buffer
will be needed.
It was also noticed a typo in one command. MBOX_BIOS_CMD_C3_DATA_INFO is
about S3 transition, so it should be called MBOX_BIOS_CMD_S3_DATA_INFO.
BUG=b:77940747
TEST=None.
