[PATCH v5 06/50] mtd: nand: gpmi: use mtd_ooblayout_xxx() helpers where appropriate

The mtd_ooblayout_xxx() helper functions have been added to avoid direct accesses to the ecclayout field, and thus ease for future reworks. Use these helpers in all places where the oobfree[] and eccpos[] arrays where directly accessed.
