Not really a nice way to split this up further for submission. This
provides all the DRM interfacing logic, the headers and relevant glue.

Again this might be a candidate for sharing later.

Some of this should one day become a library shared by i915 and gma500 I
suspct. Best however to deal with that later once it is all nice and
stably merged.

The devices have various internal differences so we have some abstractions
to hide the ugly differences and we then wrap them up in standard
interfaces. Add these bits

We support 2D acceleration on some devices but we try and do tricks with
the GTT as a starting point as this is far faster. The GTT logic could be
improved further but for most display sizes it already makes a pretty good
decision.

This fits alongside the GEM support to manage our resources on the card
itself. It's not actually clear we need to configure the MMU at all.
Further research is needed before removing it entirely. For now we suck it
in (slightly abused) from the old semi-free driver.

The driver uses GEM along with a couple of small bits of wrapping of its
own. The only real oddity here is the support for using the 'stolen' memory
rather than wasting several MB.

We use a simple resource manager as we don't need to manage our space
intensively at all as we only do 2D work. We also have a GTT which is
entirely GPU facing so in the Cedarview case are not even allocating from
host address space.

This driver supports unaccelerated KMS display, and accelerated console
handling on the Intel Poulsbo, Oaktrail, Cedarview and Medfield hardware.

For the initial merge Medfield will be left out as it needs considerable
further work to reach a decent standard

Begin by adding the Makefiles and Kconfig. These are not yet plumbed into
the DRM layer so will have no effect on their own
