Subject: [RFC/PATCH v2 03/16] dt-bindings: soc: bcm: bcm2835-pm: Add support for bcm2711

Add a new compatible string for BCM2711 and the option to provide a
third reg property for the board's new Argon ASB.

In BCM2711 the new Argon ASB took over V3D, which is our only consumer
of this driver so far. The old ASB is still be present with ISP and H264
bits but no V3D.
