netifd does not handle network.@device[x].name properly if it
contains multiple ifaces separated by spaces. Due to this, board.d
lan_mac setup does not work if multiple ifaces are set to LAN by
ucidef_set_interface_lan.
To fix this, create a device node for each member iface when
running config_generate instead.
