Add mapfile.csv and power8.json files for the Power8 processor.
Changelog[v3]
- [Namhyung Kim] Remove text from PublicDescription fields if it is
identical to or prefix of BriefDescription.
Changelog[v2]
- [Andi Kleen] Replace the vendor-family-model,version fields with
cpuid,version fields (to simplify mapfile)
- Reuse the JSON files when possible (i.e multiple cpuids can refer
to the same JSON file) - so drop the 004d0100.json and use
power8.json in multiple entries in mapfile.
- Add few more Power8 PVRs to mapfile
Changelog[v21]
- Group events into per topic per cpu model.
