omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and 'dma_channel' are never referenced by the NAND driver, yet various board files are initializing those fields. This is both incorrect and confusing, so remove them. This allows to get rid of a global variable in gpmc-nand.c. This also corrects an issue where some boards are trying to pass NAND 16bit flag through .options, but the driver is using .devsize instead and ignoring .options. Finally, .dev_ready is treated as a flag by the driver, so make it bool instead of a function pointer.
