mtd: rawnand: plat_nand: Pass a nand_chip object to all platform_nand_ctrl hooks
Let's make the raw NAND API consistent by patching all helpers and hooks to take a nand_chip object instead of an mtd_info one or remove the mtd_info object when both are passed. In order to do that, we first need to update the platform_nand_ctrl hooks to take a nand_chip object instead of an mtd_info. We add temporary plat_nand_xxx() wrappers to the do the mtd -> chip conversion, but those will be dropped when patching nand_chip hooks to take a nand_chip object.
