mtd: Add bad block table overrides to Davinci NAND driver
The existing NAND infrastructure allows the default main and mirror bad block tables to be overridden in nand_default_bbt(). However, the davinci_nand driver does not support this. Add that support by adding fields to the davinci driver's platform data so platform code can pass in their own bbt's and make the davinci_nand driver honor them. Signed-off-by: Mark A.
