From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Eliminate crtc->plane since it's pretty much a layering violation.
We can always get the plane via crtc->primary if we actually need it.
The only ugly thing left is plane_to_crtc_mapping[], but that's
still needed by the pre-g4x watermark code.
Also revise the comment about emum old_plane_id to make it clear
one should not use it for SKL+ ever.
