USB: serial: option: add support for Novatel MiFi USB620L

commit e07af133c3e2716db25e3e1e1d9f10c2088e9c1a upstream.

Also known as Verizon U620L.

The device is modeswitched from 1410:9020 to 1410:9022 by selecting the
4th USB configuration:

 $ sudo usb_modeswitch –v 0x1410 –p 0x9020 –u 4

This configuration provides a ECM interface as well as TTYs ('Enterprise
Mode' according to the U620 Linux integration guide).
