The two option here are drm tree via gvt and i915 trees or the vfio
tree, neither of which really is my tree.

We already have a fair bit of vfio changes at the tail end of the series,
and Jason has some more that should sit on top of it, and I have some
more that I haven't sent yet.

So if we could get the MMIO table and Makefile cleanups into a topic
branch that we could pull into the vfio tree and merge it through that
that would seem easiest to me, assuming that is ok with the i915, drm
and vfio maintainers.
