We cannot use board.json data here: this code is called before mounting
the rootfs, in the preinit.

Also, the switch is actually registered, just vlans are not needed on
HT-TM02 for normal operation and thus are normally disabled.

Also, the LAN and only port is 4, so by adding just 0 to the failsafe
vlan then the failsafe is broken for this router.

We could detect that the LAN port is 4 here, but this code is still
not needed for this router. Furthermore, this creates an useless eth0.1
interface that is visible in eg. ifconfig even when failsafe is not
triggered. This may create problems with bridging since LAN VLAN 1
would not be passed to the br-lan bridge (and thus to the WLAN, in
the default config) anymore. This will break WLAN VLAN trunking for
