Subject[PATCH 5/9] tracing: Convert some power events to DEFINE_EVENT
Use TRACE_EVENT_TEMPLATE 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
