[ARM] 3395/2: AT91RM9200 Dataflash Card vs MMC selection

Patch from Andrew Victor

On the Atmel AT91RM9200-DK and -EK boards, a pin is used to control
whether the card socket is used for a DataFlash Card or an MMC/SD card.

We now default to MMC/SD in the configuration files.

(This version of the patch can be applied before Patch 3392/1)
