6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher alexander.deucher@amd.com
commit d420c857d85777663e8d16adfc24463f5d5c2dbc upstream.
Always reprogram the hardware state on init. This ensures the PMFW state is explicitly programmed and we are not relying on the default PMFW state.
