drm/amd/display: Switch DMCUB notify idle command to NO_WAIT
[Why]
Race condition between notification of driver idle and the command being
processed. We could theoretically enter idle between the submission and
the wait for idle that occurs after.
[How]
Switch the notification to NO_WAIT to avoid the RPTR access.
