staging: gma500: Resync the patch queue with GregKH's space cleanup.

Remove all sorts of bits we can get rid of. We are now a very simple KMS
driver relying on the stolen memory for our framebuffer base (which is for
the moment hardcoded).

To support multiple frame buffers and some accel bits we will need some kind
of memory allocator, possibly a minimal use of GEM.
