ar71xx: fix default network config of WZR-HP-G300NH and CR3000

The network defaults for the WZR-HP-G300NH and CR3000 models wrongly set the
lan interface to a vlan tagged device while the switch was set up in untagged
mode, leading to broken lan side ethernet connectivity by default.

Fix the issue by emitting untagged interfaces, consistent with the switch
setting on the device.
