Commit 310e782a99c7 ("platform/x86/amd: pmc: Utilize SMN index 0 for driver probe") switched to using amd_smn_read() which relies upon the misc PCI ID used by DF function 3 being included in a table. The ID for model 78h is missing in that table, so amd_smn_read() doesn't work. Add the missing ID into amd_nb, restoring s2idle on this system.
