fbdev: framebuffer support for HTC Dream 

Add a framebuffer driver for Qualcomm MSM/QSD SoCs, tested on HTC Dream
smartphone (aka T-Mobile G1, aka ADP1).

Brian said:

  I did the original quick and dirty version for bringup.  Rebecca took
  over and (re)wrote the bulk of the driver, getting things stable for
  production ship of Dream and Sapphire, and Dima is currently adding
  support for later Qualcomm chipsets (QSD8x50, etc).
