Pixhawk Internal Compass Calibration

horror, today I read that Piwhawk Radiolink is not compatible with firmware version 4.xx
:sleepy:

Given this find - should we move RadioLink autopilots under “Discontinued Boards”?

I can make the change and submit a merge request if everyone agrees.

No surprise. They are not respecting the GPLv3 license anyway so good riddance.
