sched: Update min/max capacity for the CPUFREQ_CREATE_POLICY notifier
Following the change "57e2905 sched: Skip resetting HMP stats when
max frequencies remain unchanged" the scheduler fails to update
min/max capacities appropriately when CPUs are hot added after being
hot removed. Fix this problem by handling the CPUFREQ_CREATE_POLICY
notification and explicitly updating min/max capacities.
