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).
