I am about to stuff more objects into the plane_config and would like to
have it clean up after itself. Move the current framebuffer release into
a common function so it can be extended with the new object with
relative ease.

As only the display codes tries to pin its preallocated framebuffer into
an exact location in the GGTT, remove the convenience function and make
the pin management explicit in the display code. Then throughout the
display management, we track the framebuffer and its plane->vma; with
less single purpose code and ready for first class i915_vma.

In doing so, this should fix the BUG_ON(vma->pages) on fi-kbl-soraka.

Ville, you mentioned you had a plan... This should prevent an oops during
boot for kbl-soraka, so it would be nice :)

Was slighly worried whether the gen2/3 special case would be needed
here, but I doubt we could get this far on those anyway since the
BIOS will be using VGA mode anyway. And even if we did I guess there's
no real way we wouldn't be able to get the fence.

Moved here from pin_and_fence() I guess. Do we overwrite the PTEs
when we pin the vma? Or just assuming they already match this?
IIRC we anyway assume that ggtt has a 1:1 mapping of stolen at this
point and we don't double check that the PTEs really point to stolen.

Looks all right to me. Series is

We rewrite the PTE on binding; we don't assume the current entries point
anywhere.

Right. We assume the layout is straightforward, and we don't actually
write the PTEs until later when initialising the GTT (after reserving
all the holes required for preallocated objects). Well that's the plan
at least.

This patch will introduce a change where we rewrite the PTEs
immediately. But either they already pointed to our preallocated stolen,
or we are already in trouble.
