devicetree: hwmon: shtc1: add sensirion,shtc1.yaml
Add documentation for the newly added DTS support in the shtc1 driver. To align with the drivers logic to have high precision by default a boolean sensirion,low-precision is used to switch to low precision.

+title: Sensirion SHTC1 Humidity and Temperature Sensor IC
+
+maintainers:

+
+description: |
+ The SHTC1, SHTW1 and SHTC3 are digital humidity and temperature sensor
+ designed especially for battery-driven high-volume consumer electronics
+ applications.
+ For further information refere to Documentation/hwmon/shtc1.rst
+
+ This binding document describes the binding for the hardware monitor
+ portion of the driver.
