Subject: cpuidle: psci: Support hierarchical CPU idle states
Git-commit: f08cfbfa4fb1b5cf15d9f3d3f8ef2280236f4a12
Patch-mainline: v5.6-rc1
References: jsc#SLE-12251
Currently CPU's idle states are represented using the flattened model.
Let's add support for the hierarchical layout, via converting to use
of_get_cpu_state_node().
