perf/x86/intel/uncore: Convert to hotplug state machine
Convert the notifiers to state machine states and let the core code do the
setup for the already online CPUs. This notifier has a completely undocumented
ordering requirement versus perf hardcoded in the notifier priority. This
odering is only required for CPU down, so that hardware migration happens
before the core is notified about the outgoing CPU.
