Uavcan update (#3424)

* [uavcan] Start updating UAVCAN to latest version.
Now renamed DroneCAN.

* [uavcan] Update airspeed.

* [uavcan] Update power.

* [uavcan] Update range sensor.

* [uavcan] WIP actuators.

* [dronecan] Fix makefile for new installations

- The Makefile doesn't execute the .sync .update when added to the .PHONY section
- The DSDL folder doesn't exist before the .sync .update of the DSDL

* [can] Add documentation for USE_CANx define and fix dronecan

* [dronecan] Update actuators

* [dronecan] Cleanup actuator feedback
