It's not exported to drivers so they don't play games in their own
ioctls or do something else than the atomic set/get_property hooks. I
guess we could export, but I think here the better solution is to lift
the legacy gamma compat function to core code status, since I think
that's the direction we want to go anyway. Bit more churn since the
name changes.
