[PATCH v1 2/4] dt-bindings: power: supply: bq25890: Add input voltage limit

[Vincent Cloutier]

From: Vincent Cloutier <vincent at cloutier.co>

Document input-voltage-limit-microvolt for configuring the absolute input
voltage dynamic power management threshold. When the property is absent,
the charger retains its relative VINDPM behavior.
