OpenWrt has recently added the "network" LED trigger to support routers
that have a single WLAN LED for multiple phys.
This patch replaces the temporary workaround used during initial
support, where the LED was triggered only by activity on a single phy.
With this change, the WLAN LED on the ipTIME AX3000SE now correctly
indicates activity on both `phy0` and `phy1`.
