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. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
