Update for the fact that pm_active and pc_cpumask were changed to cpuset_t.

Browse Source 
This now calculates pc_cpumask based on pc_cpuid itself as the former is
slated for being deorbited.
This branch now at least boots UP again. MP needs more things converted and
the existing conversion from cpumask_t to cpuset_t still has bugs.
