[Intel-gfx] [RFC PATCH 00/10] refactor display structs a little bit

[Dave Airlie]

I had reason to look at i915 display again recently, and how tied
to the core driver the whole thing is.

I think it at least could benefit from starting to move display
specific things out into a separate display structure. This
could later be made optional or at least separated out in better
ways using internal APIs perhaps.

I've pretty much picked some random stuff to demonstrate, and there
should be no functional change with this, and of course there are
plenty of things left to move later.

Dave.
