Telit xE910 is a family of modems from 2g (GE910) through 3.5g
(HE910, UE910, DE910) to 4g (LE910).
They share a common programming interface.
So move he910 plugin to more generic xe910
and add support for UE910 (i was able to test on it).
Also differentiate between variants in terms of voice calling
and built-in GPS.

Telit modems HE910 and UE910 share the same USB
vendor and device IDs (1bc7:0021) but they are
different devices.
HE910 is HSPA Class 14/6 and UE910 is Class 8/6.
Both come in voice-enabled variants.
HE910 also comes in variants with built-in GPS.
