mtd: nand: Introduce CONFIG_SYS_NAND_BUSWIDTH_16BIT
Introduce CONFIG_SYS_NAND_BUSWIDTH_16BIT option so that other NAND controller drivers could use it when a 16-bit NAND is deployed. drivers/mtd/nand/ndfc has CONFIG_SYS_NDFC_16BIT, so just rename it, so that other NAND drivers could reuse the same symbol.
