[PATCH v3 5/6] dt-bindings: mfd: da9062: add regulator gpio enable/disable documentation

[Marco Felsch <m.felsch@xxxxxxxxxxxxxx>]

At the gpio-based regulator enable/disable documentation. This property
can be applied to each subnode within the 'regulators' node so each
regulator can be configured differently.
