Even though their domain-idle-state configurations are identical, sharing one power-domain node means the kernel's PSCI domain idle refcounting merges both clusters together, preventing either cluster from entering idle independently. Split cluster_pd into cluster0_pd and cluster1_pd so each cluster is tracked separately by the PSCI domain idle logic.
