Subject: [PATCH v2] USB: serial: option: add Fibocom L7xx modules

Add support for Fibocom L716-EU module series.

L716-EU is a Fibocom module based on ZTE's V3E/V3T chipset.

Device creates multiple interfaces when connected to PC as follows:
- Network Interface: ECM or RNDIS (set by FW or AT Command)
- ttyUSB0: AT port
- ttyUSB1: Modem port
- ttyUSB2: AT2 port
- ttyUSB3: Trace port for log information
- ADB: ADB port for debugging. ("Driver=usbfs" when ADB server enabled)

Here are the outputs of lsusb and usb-devices:
$ ls /dev/ttyUSB*
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3
