    brcm47xx: fix switch port mapping on Asus RT-N12 and RT-N16 models
    
    On Asus RT-N12 and RT-N16 models, the WAN and LAN4 ports are swapped in the
    initial switch configuration since the presets present in nvram appear to be
    wrong.
    
    Add special casing for these models to detect_by_model() in order to ensure
    a proper switch configuration.
    
    Fixes FS#502.
