drm/amdgpu: refine uvd5.0/6.0 code. 



1. delete redundant cg pg mask check.
   pg mask use to ctrl power on/down uvd.
   not start/stop uvd.
   cg mask will be check when enable mgcg.
2. no need to start uvd when initializ.
   when ring test/ib test/encode, uvd was enabled.
   when uvd idle, uvd was stopped.
3. chang cg pg sequence in powerplay.
