Subject: [PATCH v2 net-next]  net: mhi: Set wwan device type

The 'wwan' devtype is meant for devices that require additional
configuration to be used, like WWAN specific APN setup over AT/QMI
commands, rmnet link creation, etc. This is the case for MHI (Modem
host Interface) netdev which targets modem/WWAN endpoints.
