ramips: use WiFi LED DT triggers for TP-Link RE650 v1

This moves WiFi LED triggers from 01_leds to device tree.

While at it, convert the labels there to lower case; this is
more commonly used and the change will actually remove competition
between DT trigger and leftover uci config on already installed
systems.
