[PATCH v10 13/27] drivers: firmware: psci: Support hierarchical CPU idle states

[Ulf Hansson]

From: Lina Iyer <lina.iyer@xxxxxxxxxx>

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().
