[PATCH v6 2/4] dt-bindings: hwmon: Add Sensirion SHT30 series

[Zaixiang Xu <zaixiang.xu.dev@gmail.com>]

Add YAML devicetree binding schema for Sensirion SHT30 series and the
compatible GXCAS GXHT30 sensors.

Use fallback compatibles for compatible chips and add optional
interrupts and vdd-supply properties.
