    ath79: TP-link TL-WR1043ND v2/v3: use fixed-link for AR8327 switch connection
    
    Attaching PHY driver to the switch, while adding LEDs binding causes the
    PHY driver to create additional LED instances, handled incorrectly by
    the PHY driver, which are non-functional. Use fixed-link to attach the
    switch driver, instead of PHY driver, to prevent that.
    
    This has a side effect of not logging switch port up/down events in the kernel
    log.
