Voltage monitoring functionality is self-contained and requires no supply- or battery-specific runtime configuration. Battery design characteristics (e.g. voltage-min-design-microvolt) are useful for users to understand the charge level and are commonly provided by a separate battery node linked with monitored-battery property. Add reference to power-supply.yaml so that power-supplies and monitored-battery properties become available. Further drop reg property description and replace it with maxItems 1 as is common for i2c devices with single bus address. Finally replace additionalProperties with unevaluatedProperties to allow properties from referenced schemas.
