[PATCH V1 2/3] dt-bindings: power: sbs-battery: add polling interval property

[LI Qingwu]

Add the optional sbs,monitoring-interval-ms property for SBS-compliant
batteries to configure a periodic polling interval on systems without
interrupt support. The driver periodically checks the battery status and
notifies userspace of changes when this property is set, and ignores it
when a GPIO interrupt is available.

The property defaults to 0 to preserve existing behaviour.
