[RFC PATCH v1 2/4] dt-bindings: iio: flow: add Sensirion SLF3x liquid flow sensor

[Wadim Mueller <wafgo01@gmail.com>]

From: Wadim Mueller <wadim.mueller@cmblu.de>

Add a DT binding for the Sensirion SLF3x family of I2C liquid-flow
sensors.  A single 'sensirion,slf3s' compatible is exposed because
the sub-types share the same register map and are detected at
runtime via the product-information register.

+description: |
+  Family of digital liquid-flow sensors from Sensirion with I2C interface.
+  The same register map is shared by all family members; sub-types differ
+  only in the flow scale factor exposed by the device and are detected at
+  probe time via the product-information register.
+
+  Supported sub-types:
+    - SLF3S-0600F (calibrated range ±2 ml/min)
+    - SLF3S-4000B (calibrated range ±80 ml/min)
