[PULL][Xenial] PMU updates for ARM

[Dann Frazier]

These backports accomplish a couple of things:
 1) It makes ARM PMU events self-describing so that they show up in
'perf stat' output
 2) Adds support for the Cavium ThunderX PMU.

See the following bugs for more details:

Tested on Cavium ThunderX and Calxeda Highbank (for the armhf pieces).
