comgt: ncm: allow specification of interface name
Add ifname property to UCI, which can be used to override the autodetected interface name in case the detection fails due to having none or more than one interface exposed by the modem, which is not explicitly linked to TTY port. This is needed on certain variants of ZTE MF286R built-in modem, which exposes both RNDIS and CDC-ECM interfaces on the modem, on which the automatic detection may select the wrong network interface.
