With "operating-points-v2" its possible to tell which devices share OPPs. We already have infrastructure to decode that information.
This patch adds following APIs:
of_get_cpus_sharing_opps: Returns cpumask of CPUs sharing OPPs (only valid with v2 bindings).
of_cpumask_init_opp_table: Initializes OPPs for all CPUs present in cpumask.
of_cpumask_free_opp_table: Frees OPPs for all CPUs present in cpumask.
set_cpus_sharing_opps: Sets which CPUs share OPPs (only valid with old OPP bindings, as this information isn't present in DT).
