From: Ville Syrjälä <ville.syrj...@linux.intel.com>
Switch over to using explicit old/new planes states instead of
digging the old state out via plane->state. The main issue is that
plane->state will point to the uapi state which we generally don't
even want to look at.
Also it sets a bad example as using plane->state during commit_tail()
would be a bug. Here we're still holding the modeset locks so it's
actually safe, but best not give people bad ideas.
