Add at91 data so we can convert a PIO unit number into a base address. Add at91 standard memory controller helper functions. Generalize AT91 NAND support a bit. Connect NAND for the SAM9260EK eval board, as well as the HotE HL-201. Add nand device and NANDFS into the mix for those at91 boards that have support for it at the moment. END
