[review] EM75xx firmware update using qmi-firmware-update

[Aleksander Morgado]

Hey Bjørn & all

I've pushed a new MR to gitlab that includes support for the EM75xx
firmware update process, using the Sahara/Firehose protocols:
https://gitlab.freedesktop.org/mobile-broadband/libqmi/merge_requests/40

I've uploaded a reference example log to the MR as well. Comments and
tests (with --verbose) welcome!

P.S.: I have really done tons of failed attempts before getting the
process more or less right and consistent, and my one and only EM7565
is still alive.
