nand: Embed mtd_info in struct nand_chip
nand_info[] is now an array of pointers, with the actual mtd_info
instance embedded in struct nand_chip.
This is in preparation for syncing the NAND code with Linux 4.6,
which makes the same change to struct nand_chip. It's in a separate
commit due to the large amount of changes required to accommodate the
change to nand_info[].
