ARM: nomadik: add FSMC NAND
This adds the FSMC NAND driver and flash partitions to the Nomadik device tree. The only compatible string accepted by this driver is currently "st,spear600-fsmc-nand" which is inappropriate for this system, so this patch adds the compatible value "stericsson,fsmc-nand" as well.
