Currently, PERF_TYPE_SOFTWARE is treated specially since task-clock and cpu-clock events are interfaced through it but internally gets forwarded to their own pmus. Rework this by overwriting event->attr.type in perf_swevent_init() which will cause perf_init_event() to retry with updated type and event will automatically get forwarded to right pmu. With the change, SW pmu no longer needs to be treated specially and can be included in 'pmu_idr' list.
