…r.stop() Emiting the current frequency of all CPUs in the stop() hook is not useful as the current frequency should already be known from the trace. Either the event is emitted every time the frequency changes and the up-to-date information is available, or the frequency never changes (e.g. userspace governor) and the frequencies will be known from emitting cpu_frequency_devlib in start().
…vents dependent on the configured events Make cpu_frequency_devlib dependent on whether the "cpu_frequency" event has been selected rather than dependent on the cpufreq devlib module being loaded on the target. The old behavior became particularly problematic with the lazy loading of modules. However, it was never a reliable way of knowing if the user was interested in the frequency or not. Apply a similar mechanism for the extra idle state transitions only done if "cpu_idle" event is selected.
