There are 3 ethernet ports on Y1. LAN1 on port1, LAN2 on port0 and WAN on
port4.
Use a standalone switch configuration to match this and use the switch
trigger so that LAN LED could indicate the connetction status for both
lan ports correctly.
This patch also drop the internet led configuration, because there is a
WAN led for port4 and eth0.2 isn't always used as WAN.
