[PATCH 06/36] mtd: nand: omap: Move gpmc_update_nand_reg to nand driver

GPMC and NAND drivers share the same register space but never use the same registers. As there is no clear address seperation between the registers for GPMC and NAND, we can't easily split it up into 2 regions i.e. one for GPMC and other for NAND. Instead, we simply remap the entire register space
