[RFC PATCH 1/3] dt-bindings: iio: temperature: Add STS30 devicetree bindings

[Maxwell Doose <m32285159@gmail.com>]

Add the devicetree bindings for the STS30 family of temperature sensors.
The STS30 family of sensors includes the STS30, STS31, and STS35.

All devices in the STS30 family share the same commands, timings, etc.
The only difference between them is their measurement accuracy and
tolerance.
