Please split this into two patches. First one should nuke the
adjusted_x/y from the crtc, the second should do the skl function
unification.

As I said earlier, we'll want to get rid if this crtc->base.y thing as
well. I think it's actually semi broken at the moment since we seem to
be stuffing the unclipped coordinate in there. It should really be
the clipped one (ie. plane_state->src.y1 >> 16). So we'll want to put
that (or potentially the whole fence_offset) into the fbc cache as well.
I guess we could do that part as a separate patch though.
While I was looking at the fbc code it occurred to me that it's doing
way too much checking in the can_activate() function. Most of the checks
it's doing there we could have done already when we had the plane/crtc
states around. So I think we should pre-compute more of the answer to the
"can this plane/crtc do fbc?" question. It might allow us to nuke some
stuff from the fbc state cache as well.
