OMAP: Add support for VRFB rotation engine
VRFB rotation engine is a block in OMAP2/3 that offers 12 independent
contexts that can be used for framebuffer rotation.
Each context has a backend area of real memory, where it stores the
pixels in undisclosed format. This memory is offered to users via 4
virtual memory areas, which see the same memory area in different
rotation angles (0, 90, 180 and 270 degrees).
