drm/mediatek: Add wait_for_event for crtc disable by cmdq

Browse source

mtk_drm_crtc_atomic_disable will send an async cmd to cmdq driver,
so it may not finish when cmdq_suspend is called sometimes.

Add wait_for_event after sending async disable plane cmd to make
sure the lastest cmd is done before cmdq_suspend.
