Ayke van Laethem c765ef3970 servo: add driver using PWM
This PR adds support for controlling servos. For example, on the Arduino
Uno it should be able to control up to 6 servos jitter-free when using
all available PWM pins.

I haven't added support for setting a position in degrees, mainly
because this varies by servo and it's probably necessary to configure
the bounds in some way. Therefore, I added just SetMicroseconds. This
makes the API possible to use and leaves the possibility of adding a
SetPosition in the future.
