There are several way to improve the MUX on the IMX, but this should be
done in separate patches. This patch takes care only to move the
selected UART from the driver to the board configuration file.

This should be done globally. Agree this must be done, but I will let
that the patch remain easy to be read containing only the changes
related to the commit message. So I tend to move this cleanup in a
separate patch.
