    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
