mtd: nand: add an mtd_to_nand() helper
Some drivers are retrieving the nand_chip pointer using the container_of macro on a struct wrapping both the nand_chip and the mtd_info struct while the standard way of retrieving this pointer is through mtd->priv. Provide an helper to do that. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
