mtd: nand: omap_gpmc: Enable multiple NAND flash devices

Since the CS of a device connected to the GPMC was
stored in the global variable, it was not possible to
use multiple devices. In this patch the CS is stored per
device in its 'struct omap_nand_info'. This makes it
possible to use up to 'GPMC_MAX_CS' NAND Flash devices
connected to U-boot.
