This driver adds basic support for Aptina ar0130 1.2M sensor.
Changes for v2:
1: Include new test pattern control as pointed by Hans and Lad.
2: Remove soc_camera.h as suggested by Guennadi.
3: Change auto exposure control as pointed by Dan Rittersdorf.
4: Change incorrect return value as pointed by Nicolas.
5: Change crop and binning settings.
