WIP motor_board: Set reset position

Increase the motor movement speed.

Set a reset position in motor parameters.
With this reset position, motor can be moved to a small distance above
button, so the movement of touch/release will be shorter.

TODO: Tune the parameters for Jabra speaker.

TEST=Use test_server, call p.motor_board.Reset() and see motor is
stayed at about 2 cm above button.
TEST=Test buttons by calls like PressOneFunc('Vol Up')
