problem: previously when connecting power to Power 1, commander refused
to arm (no power source error), and when connecting to Power 2, arming
works, but power consumption was not measured (& shown in QGC).
Swapping Brick1 with Brick2 makes sure both works when connecting to
power 1.

Ideally we will have support for both power sources (including fail-over)

This enables control loops that are sensitive to vertical velocity offsets to use a vertical velocity that is kinematically consistent with the vertical position.

Adds interface for vertical position derivative

fixes a wrong index for _mag_device_id: previously, driver_index was used
(the CAL_MAG param index), but the correct index is the uorb topic
instance.

Fixes #7421

Tested with Pixracer and Zubax GNSS2.0
