    mtd: atmel_nand: Do not warn on bitflips
    
    When using multi-bit ECC, it is normal for the NAND Flash driver to
    correct bit errors during the life of the product. Those errors will
    only be cleared once a threshold has been reached, and corrections can
    occur regularly before this.
    
    Use only dev_dbg and not dev_info to report the bitflips, to keep the
    system log clean when everything works correctly.
