    mtd: nand: Add max_bb_per_die and blocks_per_die fields to nand_chip
    
    The fields max_bb_per_die and blocks_per_die are useful determining the
    number of bad blocks a MTD needs to allocate. How they are set will
    depend on if the chip is ONFI, JEDEC or a full-id entry in the nand_ids
    table.
