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
