This changes the judgement of if needing to round up the width or not, from using the `dp_flow` to the plane's type.

The `dp_flow` can be -22(-EINVAL) even the plane is a PRIMARY one. See `client_reg[]` in `ipu-common.c`.

[ 0.605141] [drm:ipu_plane_init] channel 28, dp flow -22, possible_crtcs=0x0

Per the commit message in commit: 71f9fd5bcf09, using the plane type for judging if rounding up is needed is correct.

Fixes: 71f9fd5bcf09 ("drm/imx: ipuv3-plane: Fix overlay plane width")

That id is not in Linus's tree :(
