Subject: [PATCH v2] 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/ttyUSB2.

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{0..4} appear upon connecting the FT980-KS, and allows
sending AT commands to /dev/ttyUSB2.

Changes since v1:

* Interface #3 (ADB) is blacklisted.
* NCTRL flag is set to the diag interface.

These changes (relative to v1) also allow ModemManager to recognize the
device.
