[PATCH] Infineon: Add support for Infineon / Intel modems

[Paul Bartell]

Hey Aleksander,

I don't have any modems to test ECM data mode with. Likely It could be
supported via the +XDATACHANNEL command in addition to +XCEDATA, but
It's unclear from the Sierra interface guide or Intel docs.

Either way, we will have to add more VID/PID pairs for other modems /
USB compositions to support modems with the ECM data feature.

The Telit LN930 seems to share a USB VID/PID with the HL7588 in NCM
mode, so it's probably a good idea to test with that modem as well so
that we don't break compatibility (it supposedly works with the
generic plugin as-is).

I attached a new patch that should address your other requests. Let me
know if there are any other issues or if I missed anything.
