Input: add driver for Sharp gp2ap002a00f proximity sensor
This driver adds support for Sharp's GP2AP002A00F proximity sensor. The
proximity is measured as a binary switch, i.e. an object is either
detected or not detected. Hence, this driver is implemented as a switch
that reports SW_FRONT_PROXIMITY.
