[PATCH v2 2/5] base-files: failsafe: Fix IP configuration

[Hauke Mehrtens]

Adapt the preinit_config_board() to the board.json network changes. It
now looks for the device and the ports variables to configure the LAN
network.

This works with swconfig configurations.

Fixes: FS#3866
Fixes: d42640e389a8 ("base-files: use "ports" array in board.json network for bridges")
