Subject: [PATCH] USB: serial: option: Add Telit FT980-KS composition

This commit adds the following Telit FT980-KS composition:

0x1054: rndis, diag, adb, nmea, modem, modem, aux

AT commands can be sent to /dev/ttyUSB5.

Signed-off-by: Leonid Bloch <lb.workbox@...il.com>
---

The full composition is not tested, and it is the default one according
to Telit support. What is tested, is that this commit makes
/dev/ttyUSB{1..7} appear upon connection of the FT980-KS, and allows
sending AT commands to /dev/ttyUSB5.
