Attempt to pick most energy efficient wakeup in find_idlest_{group, cpu}(). Finding the optimum target requires an exhaustive search through all cpus in the groups. Instead, the target group is determined based on load and probing the energy cost on a single cpu in each group. The target cpu is the cpu with the lowest energy cost.
