drm/amd/powerplay: initialize uvd/vce powergate status v4
On UVD/VCE dpm enabled/disabled, the powergate status will be set as false/true. So that we will not try to ungate/gate them( enable/disable their dpm) again. v2: added check for uvd/vce powergate status before gating v3: fix typo in description v4: warning fix (Alex) Signed-off-by: Evan Quan <evan.quan@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
