    sched: tracing: enable TSC tracing for all events
    
    it is enabled for pretty much all of them already.
    There were just a few that had it disabled.
    
    When tracing a scheduler, timing information is
    really important, so enable it everywhere scheduling
    related.
    
    Note that this was not really a problem if looking
    at the traces with xenalyze, but it was if using
    xentrace_format.
