mtd: nand: Add and use static inline wrapper for getting nand_chip from mtd
All drivers in tree use mtd->priv for the nand_chip. Add and use a static
inline wrapper mtd_to_nand() which we already have in the kernel for
getting the nand_chip from the mtd_info struct. Next step would be to
embed a struct mtd_info into struct nand_chip.
