Update smartsensor pin definitions for hardware PWM

Originally the pinout of the smart sensors did not have hardware
PWM pins used for servos or for the battery buzzer. Since it is

The battery buzzer sends voltage measurements to the controller board
as well as sounding an audible alarm if battery cell voltages are outside
an acceptable range.
Implemented smart device for line scan camera

This is a linear camera with a clk and analog voltage output that
will be used for Starwhal.
