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.
