I wasn't sure that everybody involved agreed with the patch.
@Juergen, would the patch break your platform?
Additionally, the guys from Crystalfontz didn't comment on it, but
their platform is also using a 18bit data bus width and 32bpp.

We (Free Electrons) are doing the bring up for the Crystalfontz boards,
so it's fine :)

Thanks!
