drm: Auto-set allow_fb_modifiers when given modifiers at plane initthis is done automatically as part of plane init, if drivers set the modifier list correctly. Which is the case here.
It was slightly inconsistently though, since planes with only linear modifier support haven't listed that explicitly. Fix that, and cc: stable to allow userspace to rely on this. Again don't backport further than where Paul's patch got added.

I think we can do better than linear_modifiers for overlay planes, but given that this doesn't change existing behaviour, I'll do that in a separate patch.
