Add glue to control the OMAP_LDP LCD as a frame buffer device using the
existing dispc.c driver under omapfb.

Patch updated for mainline kernel.  Note that the drivers/video/omap
should be updated to pass omap_lcd_config in platform_data.  The patch
should also be updated to compile if twl4030 is not selected, and
eventually to use the regulator framework.
