perf evlist: Remove __evlist__add_default

__evlist__add_default adds a cycles event to a typically empty evlist
and was extended for hybrid with evlist__add_default_hybrid, as more
than 1 PMU was necessary. Rather than have dedicated logic for the
cycles event, this change switches to parsing 'cycles:P' which will
handle wildcarding the PMUs appropriately for hybrid.
