Assume you meant MC7455, since I don't have any EM7455.  But that should
be about the same.  Attached a debug log from a short MBIM session,
using all the latest "qmi-over-mbim" branches:

 mm:      41708c4681b3 broadband-modem-mbim: try to use FCC Auth through QMI-over-MBIM if power up fails
 libmbim: d36c3c7f0bd8 build: bump version to 1.13.1
 libqmi: 2372f0405a66 build: bump version to 1.15.1

OK, that's not the latest libqmi commit.  I was too lazy to rebuild just
for a build fix ;)

Don't know if this is too useful.  I don't have FCC Auth enabled, and we
know that the commands are supported on the MC7455.  Anyway, the log is
here.  Only interesting piece is the NMEA noise which I still don't know
how to hide from MM.
