perf_counter: Fix up P6 PMU details
The P6 doesn't seem to support cache ref/hit/miss counts, so we extend the generic hardware event codes to have 0 and -1 mean the same thing as for the generic cache events. Furthermore, it turns out the 0 event does not count (that is, its reported that on PPro it actually does count something), therefore use a event configuration that's specified not to count to disable the counters.
