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.
