Pixhawk 4 with IRLOCK: No communication

Tom you can close the issue request @Michael_Oborne: Could you please add this note to the parameter settings in the Mission Planner: For pixhawk 4 and probaly for pixhawk 2 also, the plnd_bus is 3. This will certainly save people a lot of work. Thanks in advance Fabian
