Bug description:
[Impact]
Screen freeze after resume from suspend
[Fix]
Perform proper cleanups on UVD/VCE suspend: powergate enablement,
clockgating enablement and dpm disablement. This can fix some hangs
observed on suspending when UVD/VCE still using(e.g. issue
"pm-suspend" when video is still playing).
[Test]
1. Plug AMD RX640/Radeon 540 into the system
2. Connect with DP monitor to iGPU
3. Power on
4. Suspend the system
5. Resume from suspend
6. Do something for a while (terminal, nautilus, gnome-control-center, etc).
7. System could resume normally
[Regression Potential]
Low
