sched: take into account of limited CPU min and max frequencies
Actual CPU's min and max frequencies can be limited by hardware
components while governor's not aware of. Provide an API for them to
notify for scheduler to be able to notice accurate currently
operating frequency boundaries which helps better task placement
decision.
