sched: Convert the global wake_up_idle flag to a per cluster flag
Since clusters can vary significantly in the power and performance
characteristics, there may be a need to have different CPU selection
policies based on which cluster a task is being placed on. For example
the placement policy can be more aggressive in using idle CPUs on
cluster that are power efficient and less aggressive on clusters
that are geared towards performance. Add support for per cluster
wake_up_idle flag to allow greater flexibility in placement policies.
