DSS2: OMAPFB: Added support for the YUV VRFB rotation and mirroring.

DSS2 now requires roatation_type to be specified by driver.
Added support for that.
DSS2 OMAPFB: Modified to pass the dss mode to omap_vrfb_setup function.

VRFB size register requires the width to be halved when the
mode is YUV or UYVY.  So VRFB is modifed to pass the mode to omap_vrfb_setup
function.
