    ar71xx: fix MAC addresses on TP-Link TL-WR1043ND v4
    
    The addresses were read from the 'config' partition, which would not always
    contain the addresses at the same offsets, depending on the stock firmware
    version used before flashing LEDE. Change this to get the addresses from
    the 'product-info' partition, which is read-only.
