Add minimal support (only boot from mmc device) for the Congatec Conga-QEVAl Evaluation Carrier Board with a conga-Qmx6 module.

Signed-off-by: Leo Sartre lsartre@adeneo-embedded.com ---

Rework of the first version of the patch. All unnecessary code was removed from the board file to offer only boot from mmc. Copyright where restored (sorry for the last patch).
