drm/amd/display: Disable plane right after disconnected
HDR display playing video underflow is observed when switching to full screen due to program a lower watermark right after unlock otg. Instead of disable plane in next flip coming, if there is a plane disconnected, after otg unlock wait for mpcc idle and disable the plane, then program watermark. So there is enough warter mark to make sure current frame data pass through.
