Replaced with the more generic serial config params.

rc.mavlink contains automatic transition support that can be removed after

Replaced with the more general serial config params.

It doesn't really fit to test/, and also no other existing place.

And:
- return correct return code in SF0X::init()
- remove unneeded SF0X::probe()

Not required anymore.

- only a few configs done yet

so that params can be marked as used from scripts.

it got moved to drivers/telemetry/hott

With minimum throttle set to 0, it was not possible to control the attitude
anymore at 0 throttle, the vehicle would just stay level.

Use a templated callback method for the code parts that we actually need
templates, and avoid using a template for the rest of the code.

Make sure vehicle_air_data & vehicle_magnetometer are logged if ekf2 replay
is disabled.
