Introduce the `qcom,cpu-bound-components` boolean property for CoreSight components (TMC, Funnel, and Replicator).
This property indicates that the component is physically located within a CPU cluster power domain. Such components share the power state of the cluster and may require special handling (e.g., cross-CPU register access) compared to system-wide components.
