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.
