intel_ddi.c gets called and calls functions all over the place, so this
tries to create a bit a better interface. Our modeset code is fairly
object-oriented overall and generally big scray switch statments which
decode from the object key indicate design problems.
So for that reasons there's a few patches in here to untangle things a bit
and raise clearer barriers between the different pieces.
