drm/imx: fix YUV primary plane and IPUv3 build corner case 

- Enable color space conversion on the primary plane when the framebuffer
   format is a YUV format.
 - The IPUv3 base driver now uses drm_format_info in the PRE/PRG code. The
   PRE/PRG parts are already disabled if DRM is not available. Enforce that
   if DRM is built as a module, IPUv3 must be built as a module, too.
