ramips: fix WAN LED for D-Link DIR-810L/TRENDnet TEW-810DR

The WAN LED on DIR-810L was actually blinking on LAN1 port
activity. This has already been improved for the TEW-810DR, where
the GPIO has been set up explicitly rather than having it controlled
by the switch.

This patch also applies this setup to the DIR-810L.

In addition, the trigger in 01_leds is set up with
ucidef_set_led_switch for both devices now, so state changes should
be displayed correctly as well.
