    tracing: add latency output format option · c032ef64

    With the removal of the latency_trace file, we lost the ability
    to see some of the finer details in a trace. Like the state of
    interrupts enabled, the preempt count, need resched, and if we
    are in an interrupt handler, softirq handler or not.
    
    This patch simply creates an option to bring back the old format.
    This also removes the warning about an unused variable that held
    the latency_trace file operations.
