[Patch v4 4/6] sched/fair: update cpu_capcity to reflect thermal pressure

[Thara Gopinath]

cpu_capacity relflects the maximum available capacity of a cpu. Thermal
pressure on a cpu means this maximum available capacity is reduced. This
patch reduces the average thermal pressure for a cpu from its maximum
available capacity so that cpu_capacity reflects the actual
available capacity.
