GPMC has dedicated NAND handling blocks and have a few
registers exclusively meant for NAND operations. These
registers can be handled by OMAP NAND driver as it is
meant for handling NAND on GPMC. Update OMAP NAND
platform data with GPMC-NAND register details so that
OMAP NAND driver can handle by itself instead of
relying on GPMC exported symbols.
