[PATCH v2 12/12] mtd: nand-bbt: move nand_bbt.c to mtd folder

Since struct nand_chip is removed from nand_bbt.c, BBT is now
shareable. Both NAND and SPI NAND can use it. So move nand_bbt.c
from nand/ foler to mtd/ folder and create MTD_NAND_BBT config.
Both NAND and SPI NAND should depend on MTD_NAND_BBT.
