[PATCH 23/23] mtd: rawnand: Pass a nand_chip object nand_erase_nand()

[Boris Brezillon <boris.brezillon@xxxxxxxxxxx>]

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.

Let's tackle the nand_erase_nand() helper.
