staging: drm/omap: multiplanar and YUV support
Add support in framebuffer objects for other color formats and multi- planar YUV (NV12). Since this requires changing the API between the plane and fb for getting scanout information (paddr, etc), take advantage of the opportunity and put in place a way to allow fb's to be unpinned when they are not being scanned out. Now, before start of scanout the plane calls omap_framebuffer_pin() which takes care to pin all the backing bo's, then omap_framebuffer_update_scanout() however many times to update the scanout address(es), etc, and then when finished omap_framebuffer_unpin().
