perf timechart: Adjust perf timechart to the new power events
builtin-timechart must only pass -e power:xy events if they are supported by the running kernel, otherwise try to fetch the old power:power{start,end} events. For this I added the tiny helper function: int is_valid_tracepoint(const char *event_string) to parse-events.[hc], which could be more generic as an interface and support hardware/software/... events, not only tracepoints, but someone else could extend that if needed...
