[PATCH v7 16/26] drivers: firmware: psci: Support hierarchical CPU idle states

From: Lina Iyer Currently CPU's idle states are represented in a flattened model, via the "cpu-idle-states" binding from within the CPU's device nodes. Support the hierarchical layout, simply by converting to calling the new OF helper, of_get_cpu_state_node(). Cc: Lina
