pybricks.pupdevices.Motor: Document control here.

Browse Source 
Based on user feedback, we learned that the control attribute is used more frequently than anticipated. Therefore it makes sense to document it here, just like we do with instances of pybricks.common classes in hubs.

This makes it a bit easier to find and see how it is used, along with some of the existing examples.
