Subject: [PATCH 5/9] ARM: at91/dt: add mmc0 slot0 support to at91rm9200ek board

Add slot0 of mmc0 pinctrl pins definitions:
 - detect pin
 - write protect pin
 - enable slot0 pin: this pin is connected to an external switch which
   enable mmc0 slot0 or spi dataflash connected to cs3

The mmc0 device is not enabled, as it depends on the choosen functionnality
(spi cs3 or mmc0 slot0).
