trace: power: Adding trace events for cpufreq

Added two events to help debugging cpufreq:
1) cpufreq_sampling_event: To capture governor sampling instants
   when cpu load is evaluated and an appropriate frequency is
   selected.
2) cpufreq_freq_synced: to capture frequency synchronization of
   destination cpu with the source cpu triggered by foreground
   thread migrations.
