drm/amd/pm: send unload command to smu during modprobe -r amdgpu

Browse Source 
Send unload command to smu during modprobe -r amdgpu for smu 13/14.
1. This can fix the high voltage/temperatue issue after driver is unloaded.
2. Reloading driver could fail but with the debug port based mode1 reset
during driver is reloaded, it is good and safe.
