    realtek: add support for power LED on Netgear GS308Tv1
    
    The Netgear GS308Tv1 is already supported by OpenWrt, but is missing LED
    support. After OpenWrt installation, all LEDs are off which makes the
    installation quite confusing.
    This enables support for the green/amber power LED to give feedback
    about the current status.
