MLK-23116-14 drm/imx: dpu: plane: Remove uv_prefetch_start flag
The calling to helpers dprc_gasket_shadow_enable/disable() has
already controlled the primary(Y plane) and auxiliary(UV plane)
PRGs for their important SHADOW_EN bits. Also, it turns out
we don't need to wait FrameGen frame counter moving when only
the auxiliary PRG starts to function. So, we may remove the
uv_prefetch_start flag.
