[PATCH v2 09/16] realtek: Zyxel GS1900-8: define port LEDs

[Sander Vanheule]

The GS1900-8 had one green status LED per port. To reproduce the same
behaviour as stock firmware, the LEDs need to light up on all supported
link speeds, and blink on link activity:

    echo 1f > /sys/class/leds/green:lan-?/rtl_hw_trigger
    echo realtek-switchport > /sys/class/leds/green:lan-?/trigger
