dt-bindings: iio: light: stk33xx: add compatible for stk3013
STK3013 is a proximity sensor by Sensortek, bearing chipid of 0x31. Despite
being marketed as a proximity sensor, it also appears to have ambient
light sensing capabilities.
The part is fully compatible with the existing implementation of the
device driver. Add the compatible string of stk3013 to the existing
list, with a fallback of stk3310.
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.
In order to allow newer devices which are compatible with existing
sensors, issuing a warning for an unknown chipid indicates that
something has gone wrong with the init process, which isn't ideal.
Swap it with a friendlier info message to get things right.

* support for both raw and triggered buffer reading
* support for overflow events
* scale attributes to control voltage and current gains
* oversampling ratio attribute to control the number of integration

A use_internal_vref_attr local variable is added to make it more

pin. The other 2 modes make use of the 4.92MHz internal clock.
