[PATCH 7/10] ps3: Virtual Frame Buffer Driver

[Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>]

Add the PS3 Virtual Frame Buffer Driver.

As the actual graphics hardware cannot be accessed directly by Linux,
ps3fb uses a virtual frame buffer in main memory. The actual screen image is
copied to graphics memory by the GPU on every vertical blank, by making a
hypervisor call.
