mtd: rawnand: Pass a nand_chip object to chip->write_xxx() hooks

Browse Source 
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 all chip->write_xxx() hooks at once.
