[0/9] perf events patches for improved ARM64 support

This patchset adds support for some perf events features,
targeted at ARM64, implemented in a generic fashion.

The two main features are as follows:
- support for arch/vendor/platform pmu events directory structure
- support for parsing standard architecture pmu events

On the back of these, the Cavium ThunderX2, ARM Cortex-A53,
and HiSilicon hip08 JSONs are relocated/added/updated.

In addition, there are a patch to drop mutli-mapfile.csv support.

Differences to RFC:
- reworked patch for arch standard events
	- added arch standard event keyword support
	- use some macros to make the code more condense
	- use <linux/list_head.h>
- standardised some function names
- updated README
- for patch to support vendor subdir, add check for
  unknown dirent type
 -add patch to drop mutliple mapfile.csv support
 - dealt with new cortex a53 JSONs
