Subject: [PATCH v3 02/15] dt-bindings: soc: bcm: bcm2835-pm: Introduce reg-names

Anticipating the introduction of BCM2711, of which we'll need to support
its new RPiVid ASB, introduce reg-names into bcm2835-pm's binding. This
will help to have a consistent mapping between resources and their
meaning.
