Aside: There's a few other fb_create implementations which
simply check for valid buffer format (or an approximation thereof),
and then call drm_gem_fb_create. For atomic drivers at least we could
walk all planes and make sure the format/modifier combo is valid,
and remove even more code.
For non-atomic drivers that's not possible, since the format list for
the primary buffer might be garbage (and most likely it is).
Also delete mtk_drm_fb.[hc] since it would now only contain one
function.
