Staging: add MSM framebuffer driver

Qualcomm development of the MSM SOC framebuffer driver has
diverged significantly from the driver used by Android. This
is a snapshot of our current driver, in all it's agony. We are
putting this in staging to help with the process of converging
the two drivers.

At this point, the driver has been tested only in dumb
framebuffer mode.
