ARM: ux500: move MMC/SD/SDIO pin control to the device tree
This moves the static, device-tied pin control configuration out of the board file board-mop500-pins.c and into the device tree. Add entries for SDI1 and SDI2 on the Snowball so that the WLAN pins on SDI1 can be used further on, and the unused pins on SDI2 can be put to sleep.
