    realtek: skip SFP ports in PoE setup
    
    The function `ucidef_set_poe` receives a list of ports to add to the PoE array.
    Since switches have many ports the varibale `lan_list` is passed instead of
    writing every single lan port. However, this list includes partly SFP ports
    which are unrelated to PoE.
    
    This commits adds the option to add a third parameter to manually exclide
    interfaces, usually the last two.
