Like arm-cci, arm-ccn has the same issue where disabling preemption to avoid races between registering the PMU device and the hotplug notifier can lead to those operations taking mutexes in an invalid context. Fix it the same way by disabling hotplug instead of preemption. Since we only ever associate the PMU instance with a single CPU, we can also take the opportunity to slightly simplify the hotplug handling to track just that CPU number instead of a full cpumask.
