    ar71xx: add TP-LINK TL-WR841N/ND v12 image
    
    This router has the same hardware as TP-LINK TL-WR841N/ND v11 (same FCC
    ID, same TFTP image name...).
    
    If the stock firmware web interface doesn't accept LEDE factory image,
    it can be flashed via the U-Boot TFTP recovery mode, by long-pressing
    the reset button after power on.
    
    The TFTP image name is wr841nv11_tp_recovery.bin (yes, v11, not v12).
