Issue 106: Add a driver for the Image Processing Unit

Reported by Paul Cercueil, Aug 28, 2012

The IPU is a built-in peripheral dedicated to image processing. It 
permits to scale and convert an image using the YUV pixel format 
(and RGB on newer SoCs) to RGB, from memory to memory, or to the 
LCD.

Having a driver for that hardware in the kernel would allow us to 
offload the scaling/conversion done by video players like MPlayer to 
the hardware.

The work could start by looking at dvdk's build of MPlayer, which 
makes use of the IPU from user-space using /dev/mem. The driver 
should provide a v4l2 API.
