Subject: [PATCH 0/4] perf events vendor amd: Fixes, cleanups and updates for AMD Zen cores

This series of patches provides a fix for the broken metric and does some
cleanup for AMD Zen1/Zen2 cores. Additionally, adds Zen3 events.

The first patch fixes broken L2 Cache Hits from L2 HWPF recommended event.

The second and third patches addresses the inconsistency by defaulting all
event codes and umask values to use lower cases and 0x%02x as their
format.

The final patch adds Zen3 events.
