Use const for fb_ops to let us make the info->fbops pointer const in the
future.

Pushed up to and including this patch to drm-misc-next, thanks for the
reviews and acks.

I may have missed some pointer chasing uses of info->fbops, reported by
0day. I'll need to double check those before proceeding with the next
patch.

BR,
Jani.
