    mtd: mxc_nand: move ecc strengh setup before nand_scan_tail
    
    Since commit 6a918bade9dab40aaef80559bd1169c69e8d69cb, the mxc_nand driver
    fails with:
    
    Driver must set ecc.strength when using hardware ECC
    
    This is because nand_scan_tail checks for correct ecc strength
    settings, so we must set them up before nand_scan_tail.
