drm/imx: ipuv3-plane: Configure DMFC wait4eot bit after slots are determined
Just as the function ipu_dmfc_config_wait4eot() tells, the DMFC wait4eot bit depends on the number of DMFC slots to be used, so it should be called after the slots are determined in the function ipu_dmfc_alloc_bandwidth(). Based on tests, this patch may eliminate display distortion issue on overlay plane with small resolutions. To reproduce the issue, we may run this drm modetest case - 'modetest -P 19:64x64'.
