drivers/net/usb: Quectel EG25/EC25 modem changes for QMI WWAN

This commit tweaks support for Quectel EG25/EC25 module in the qmi
code. It add zero length path support as part of the driver info
and registers the EG25/EC25 as part of the quirks on the usb serial
interfaces since it seems to have been missing.
