drm/amdgpu/vcn: Update vcn.cur_state during suspend
Replace vcn_v1_0_stop with vcn_v1_0_set_powergating_state during suspend, to keep adev->vcn.cur_state update. It will fix VCN S3 hung issue. Signed-off-by: James Zhu <James.Zhu@amd.com> Reviewed-by: Leo Liu <leo.liu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
