iio: light: stk3310: add support for stk3013

Add support for Sensortek's STK3013 in the driver. The part bears the
product ID 0x31.

As seen in [1], Sensortek lists STK3013 as a proximity sensor. But it
has been experimentally observed that they do have ambient light sensing
capabilities. Furthermore, [2] implements a proximity and ambient light
sensor driver for STK3x1x devices, which is also indicative of the fact
that these parts are also ambient light sensors.
