I apologize,
it seems that I forget to make last step during yesterday bisection.
Here is what git bisect produces:
561a5c83eadde747253924be2f7be9070841b7c0 is the first bad commit

drm/amd/pp: Unify powergate_uvd/vce/mmhub to set_powergating_by_smu
Some HW ip blocks need call SMU to enter/leave power gate state.
So export common set_powergating_by_smu interface.
1. keep consistent with set_clockgating_by_smu
2. scales easily to powergate other ip(gfx) if necessary
