net: usb: qmi_wwan: add Compal EXC-T1 support

The Compal EXC-T1 is a Qualcomm MDM9207-based LTE modem which reports
"EXC-x1" as its USB product string. It exposes its QMI function on
interface 5.

Add a fixed-interface match for the QMI function.

Tested on a Compal EXC-T1 modem using an Ubuntu kernel build. Interface
5 bound to qmi_wwan and exposed cdc-wdm2 and wwan1.
