[PATCH v4 1/5] mtd: nand: Create a BBT flag to access bad block markers in raw mode

Some controllers can access the factory bad block marker from OOB only when they read it in raw mode. When ECC is enabled, these controllers discard reading/writing bad block markers, preventing access to them altogether. The bbt driver assumes MTD_OPS_PLACE_OOB when scanning for bad blocks. This
