soc/amd/picasso: Use PSP Sx command only for S3

Skip sending MboxBiosCmdSxInfo for sleep states other than S3.  The
PSP only acts on S3 and ignores all others.  As a result, the command
register is not cleared upon return and coreboot reports a timeout.

BUG=b:153622879
TEST=Use halt from command line, verify command skipped.
