Subject: drm/nouveau: Don't set allow_fb_modifiers explicitly
From: Daniel Vetter <daniel.vetter@xxxxxxxx>
commit cee93c028288b9af02919f3bd8593ba61d1e610d upstream.

commit 890880ddfdbe256083170866e49c87618b706ac7

drm: Auto-set allow_fb_modifiers when given modifiers at plane init
this is done automatically as part of plane init, if drivers set the
modifier list correctly. Which is the case here.
Note that this fixes an inconsistency: We've set the cap everywhere,
but only nv50+ supports modifiers. Hence cc stable, but not further
back then the patch from Paul.
