powerd - Do a more sophisticated domain scan, use kern.usched_global_cpumask
* Do a more sophisticated domain scan, cpu domains do not necessarily start
at 0.
* Handle the case where multiple cpus may belong to a single domain.
* Dynamically adjust kern.usched_global_cpumask to the number of cpus we
are running at max frequency, leaving the remaining cpus set at their
lowest frequency and left mostly idle.
* Tested on the 48-core monster and phenom x 6.
