mtd: nand: lpc32xx: 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.
