soc/amd/picasso: Fix the PSP SMI trigger info
Align coreboot's PSP MboxBiosCmdSmmInfo setup to how AGESA's PSP
library was implemented. The trigger address must be an SMI trigger
register. Assign one of the reserved triggers to the PSP.
The #define of SMITYPE_PSP 33 is still correct and is intentionally
unmodified.
This patch should be innocuous as the system doesn't currently support
SMI-based features of the PSP. The call only exists so the PSP will
honor a mailbox command during S3 suspend.
BUG=b:171815390
TEST=Run SST on Morphius
