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).
