Every member of a cluster carries the property, including the instance owning the shared resources, which references itself; instances referencing the same node form one cluster that boots in order and is torn down as a single unit. The relationship is described with a phandle rather than by containment in a parent node, as ti,k3-r5f-rproc and xlnx,zynqmp-r5fss do, because the hardware does not express it by containment either: the three QDSP6SS blocks are register-independent, with no shared register window for a container node to describe. Also add the qcom,nord-adsp1-pas and qcom,nord-adsp2-pas compatible strings used by the non-root cluster members.
