We don't show messages in the logs about unable to probe other
device types by default, MM should be no different.
This gets rid of this message coming up every fwupd startup on a
EM05-G:
"failed to probe MM device: modem cannot be put in programming mode"
This allows creating the silo when starting the engine with custom
plugin keys such as WacomI2cFlashBaseAddr.
If we move the plugin initialization earlier then we don't get the
HwID matches, so we really do have to split this into a 4-stage startup,
e.g. ->load(), ->init(), ->startup() and ->coldplug().
Quectel EG25-G modem in the Pine64 PinePhone and PinePhone Pro can be
booted with the eg25-manager (user space) or modem-power (kernel space).
We only support the eg25-manager for upgrading these modems.
Based on a patch by Dylan Van Assche <me@dylanvanassche.be>, thanks.
tristate features will automatically disable if dependencies marked
as required are missing.
Packagers can manually override using `auto_features`.

When fastboot is used, the modem is rediscovered through udev
after upgrading. However, the modem-manager plugin did not mark
the modem as unhibited with ModemManager. This resulted into
ModemManager not exposing the modem without restarting ModemManager or
rebooting the device.
Mark the modem as uninhibited and do not take ownership over the
plugin data as this caused segfaults.
Some modems such as the Quectel EG25-G have alternative firmwares available.
Read the firmware branch if supported by the firmware and set it,
if not, fall back to the default branch.
Normally each AT command is ended with either OK or ERROR,
but that's not the case for the Quectel EG25-G's AT command to enter fastboot.
As soon as AT+QFASTBOOT is sent, the modem switches to fastboot mode without replying OK.
We were calling g_module_symbol() 2703 times, which is actually more
expensive than you'd think.
It also means the plugins are actually what we tell people they are:
A set of vfuncs that get run. The reality before that they were dlsym'd
functions that get called at pretty random times.
It may make sense to have the modem not doing anything during the upgrade,
so the inhibition would make total sense.
