vendor provided pmu-events tables and sundry cleanups. The vendor pmu-events tables provide counter descriptions, default sample rates, event, umask, and flag values for all the counter configuration permutations. Using this gives us: - much simpler kernel code for the MD component - helpful long and short event descriptions - simpler user code - sample rates that won't overload the system Update man page with newer sample types and remove unused sample type.
