Patrick Fay 6b1202ee54 Perf: arm64: disable irq for hotplug offline ...

Currently the hotplug notifier calls cpu_pmu_enable_percpu_irq
when a CPU comes online. The notifier doesn't have a corresponding
call to cpu_pmu_disable_percpu_irq when the CPU goes offline.
Change the code to follow what was done in 3.18 including
tracking whether the PMU is active and the IRQ number in use.
