sched: add hook for platform-specific CPU power information
To enable power-aware scheduling, provide a hook/infrastructure
for platforms to communicate CPU power requirements for each
supported CPU frequency. This information is then used to estimate
the cost of running a task on a given CPU.
Currently, an assumption is made that the task will be running
by itself on the CPU. Given the current policy tries to spread
tasks as much as possible this assumption should not be too
far off.

[joonwoop@codeaurora.org: return rq->capacity as power cost with
sched_use_pelt=1. se.avg.runnable_avg_period is deprecated and
power_cost() will be changed by subsequent change anyway./
