drm/amdgpu: refine uvd gate logic for CI.

Browse Source 
uvd dpm will be controlled by uvd.
dpm just disable uvd dpm in case of suspend when play video.
due to the new logic of uvd_begin_use/end_use,
if disable uvd dpm in late init, will have no chance to
enable uvd dpm after resume until play video again.
