[PATCH] drm/mxsfb: Make supported modifiers explicit

[Guido GÃnther]

In contrast to other display controllers on imx like DCSS and ipuv3
lcdif/mxsfb does not support detiling e.g. vivante tiled layouts.
Since mesa might assume otherwise make it explicit that only
DRM_FORMAT_MOD_LINEAR is supported.
