Subject: Revert: drm/amd/pm: fix the high voltage and temperature issue
This was supposed to fix the high voltage and temperature issue after the driver is unloaded on smu 13.0.0,
smu 13.0.7 and smu 13.0.10, but introduced an arguably more annoying issue. Let's revert it until a proper fix is offered.
Fixes rdna3 shutdown/reboot hang.
