MX51: Add IPU driver for video support
The patch is a porting of the IPU Linux driver developed by Freescale to have framebuffer functionalities in u-boot. The port is based on kernel 2.6.31 commit cc4fe714041805997b601fe8e5dd585d8a99297f, as delivered by Freescale [i.MX BSP]. Most features are dropped from the original driver and only LCD support is the goal of this porting. Signed-off-by: Stefano Babic <sbabic@denx.de>
