USB: serial: option: add Telit FN920C04 ECM compositions
Add support for the Telit Cinterion FN920C04 module when operating in
ECM (Ethernet Control Model) mode. The following USB product IDs are
used by the module when AT#USBCFG is set to 3 or 7.

Adding these IDs allows the option driver to automatically create the
corresponding /dev/ttyUSB* ports under ECM mode.
Tested with FN920C04 under ECM configuration (USBCFG=3 and 7).
