[imx-drm] YUV on the first primary plane is misinterpreted as RGB

Hello,

if the fb on the first primary plane has pixel format YUV, the planes
was misinterpreted as RGB. The y-plane is red, the u-plane is green and
the v-plane is blue. On the overlay plane it works right. But I need
the overlay plane for OSD. I tested with linux-4.9-rc7
and pza/linux imx-drm/next on Matrix TBS2910.

How can I change to crtc 29? There are also a primary and a overlay
plane. Is anywhere a howto?

Best regards Jens.
