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.
