Douglas Raillard eb9e0c9870 collector/ftrace: Make emitting cpu_frequency_devlib and extra idle events 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.
