Subject: [PATCH v4 1/2] dt-bindings: power: supply: Add STC3117 Fuel Gauge

The STC3117 provides a simple fuel gauge via I2C.
Add a DT schema to describe how to set it up in the device tree.

+description: |
+  The STC3117 includes the STMicroelectronics OptimGauge algorithm.
+  It provides accurate battery state-of-charge (SOC) monitoring, tracks
+  battery parameter changes with operation conditions, temperature,
+  and aging, and allows the application to get a battery state-of-health
+  (SOH) indication.
+
+  An alarm output signals low SOC or low voltage conditions and also
+  indicates fault conditions like a missing or swapped battery.
+
+  Datasheet is available at
+  https://www.st.com/resource/en/datasheet/stc3117.pdf
