Current the MMC support will enable MCI port A, Which is only exist for 2mmc board. So by default we need to disable MMC (port A) support. And only enable it for 2mmc board. Otherwise, dataflash won't work in at91sam9260ek board as MMC has confliction with Dataflash in the CLK pin.

If removed this default configuration file, we can not use mmc at all, am I right?
