This looks strange - you should pass this the total number of crtcs
(the same that eventually ends up in dev->mode_config.num_crtc), not
0. And the assignement of cursors to crtcs looks a bit strange on
first read-through, but I have no clue about the sti hw. And in any
case those pointers really only matter for backwards compat with
existing pageflip and cursor ioctls, so doesn't really matter too
much.

Anyway didn't spot anything else which would need to be upgrade to
never kms interfaces, so ack from my side for that. Only looked at
that since right now I'm refreshing drm docs in those areas ;-)
