drm/amdgpu: optimize RLC powerdown notification on Vangogh

2023-11-29T22:55:47+00:00

The smu needs to get the rlc power down message to sync the rlc state with smu, the rlc state updating message need to be sent at while smu begin suspend sequence , otherwise SMU will crash while RLC state is not notified by driver, and rlc state probally changed after that notification, so it needs to notify rlc state to smu at the end of the suspend sequence in amdgpu_device_suspend() that can make sure the rlc state is correctly set to SMU.
