Telit ME910 modem

Telit ME910 ECM composition 0x1102
This composition is made of a diagnostic port (USB interface #0), two modem ports responsive to AT commands (#1, #2) and a CDC-ECM network interface, automatically bound to cdc_ether driver.
The ECM composition is mainly targeted to low-end Linux systems where there’s no chance to use the default rmnet composition 0x1101 (or the features provided by the rmnet device are not needed).
