OMAP FBDEV:Add VRFB framebuffer mirroring support for OMAP SDP 3430

This patch Should apply on top of rotation patch to enable the mirroring feature.This patch provides mirroring support for OMAP SDP 3430. You will have to append video=omapfb:rotate=0 parameters to your u-boot arguments to get this working. This supports 0,90,180 and 270 degree mirroring.
