These are part of a longer series that has been submitted some time
ago for the frame buffer tree, but it was never accepted there.
The first two of the five patches are bug fixes, so let's merge
this through arm-soc to get a working 3.9 kernel for at91.

* commit '67cf9c0a':
  ARM: at91: fix LCD-wiring mode
  atmel_lcdfb: fix 16-bpp modes on older SOCs
