[PATCH 0/6][SRU Artful] Add support for ThunderX2 vendor PMU events

[dann frazier]

BugLink: https://bugs.launchpad.net/bugs/1747523

All clean cherry-picks except patch 2/6, which required some minimal
backporting (details are documented in the S-o-b area). Tested on a Cavium
Sabre board, and regression tested on x86 (Dell XPS13 9350).
