MLK-23116-13 drm/imx: dpu: plane: Set prefetch_start flag when DPRC REPEAT_EN is disabled
A DPRC manual mode to auto mode switch is needed, when we start to enable
the DPRC with zero REPEAT_EN. Likely, the later waiting for FrameGen
frame counter moving sync-up logic is also needed, which doesn't hurt
to do so even if it's not needed. So, set the prefetch_start flag
in this case to make all these things happen.
