mtd: nand: Store nand ID in struct nand_chip
Store the NAND ID in struct nand_chip to avoid passing id_data and id_len as function parameters. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Acked-by: Richard Weinberger <richard@nod.at> Reviewed-by: Marek Vasut <marek.vasut@gmail.com>
