Add value scaling for energy events on A64FX, see https://github.com/fujitsu/A64FX/blob/master/doc/A64FX_PMU_Events_v1.3.pdf

* Check perf device path for ARM8 A72 with fallback. Fixes #425

* Add translate types for Arm8 A72

* Add min,max,sum,instant calculations for Nvidia PerfWorks

* Use LIKWID's debug/error macros instead of fprintf

* Initialize GPU topology and nvmon only if needed. Fixes #427

In bash (and other shells), the leading `$` in `$VERSION=stable` will fail.
The correct variable assignment looks like:

```sh
VERSION=stable
```

Furthermore, if `VERSION` is stable, the directory will not be
called `likwid-stable`  but (at the moment) will be `likwid-5.2.0`.
A workaround is to simply use an `*` as that will be substituted
by the the correct directory, assuming that only one
`likwid-xyz` directory exists.

* Support spaces in marker API labels

- replaces "%s" with "%Nc" where N is set to one minus
  the size of the zeroed out.
- added printout of regiontag to not valid region description msg

* Minor fix to comments
