drm/amdgpu: add HDP flush dummy for UVD 6/7
The UVD firmware doesn't seem to like the HDP flush here. This worked for years without HDP flush, so just skip it. Signed-off-by: Christian König <christian.koenig@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
