mtd: nand: Add max_bb_per_die and blocks_per_die fields to nand_chip

Browse Source 
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.
