We'll also need to do something about having all of this in
intel_display.c. Would intel_crtc.[ch] be too close to intel_crt.[ch]?
Also, intel_encoder.[ch]?
Or, move everything *else* out of intel_display.c?
Not part of this patch, obviously. Some comments inline.

That's a kind of odd ordering wrt everything else we have. I guess it's
CHV that messes up the regular order worst?
