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'.
