[PATCH 1/2] dt-bindings: power: supply: Add Silicon Mitus SM5714 fuel gauge

[Nizat Mikayilli via B4 Relay]

From: Nizat Mikayilli <nacht@xxxxxxxxxx>

The Silicon Mitus SM5714 includes a MUIC, a charger and a fuel gauge,
each at its own I2C address. Add a binding for the fuel gauge as a
separate device, like the MAX77705 fuel gauge.
