tracing: Convert some power events to DEFINE_EVENT
Use DECLARE_EVENT_CLASS to remove duplicate code:
text data bss dec hex filename
4312 524 12 4848 12f0 kernel/trace/power-traces.o.old
3455 524 8 3987 f93 kernel/trace/power-traces.o
Two events are converted:
power: power_start, power_frequency
No change in functionality.
