 Displayed image has incorrect colours.

 Alternate reproducer:

  * disable YUV support in driver, recompile, reboot,
  * use Sugar Record activity or GStreamer pipeline

 gst-launch-0.10 v4l2src ! xvimagesink

 With ov7670 sensor, the problem does not occur.

 In Open Firmware the problem does not occur.  Correct image data is

 select /camera / defaults to RGB565 mode
 .properties \ verify SIV120D

 Same sensor register settings used, so this is probably a CCIC
 configuration or data interpretation issue.
