[U-Boot] [PATCH 4/7] 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[].
