Added support for AMD. More refactoring

[Red-Eyed]

fixes #17

• Added get_avail_powersave() (and performance).
    This function returns the most energy(and performance) efficient governor.
    This should fix AMD issue when powersave is not available
    but "ondemand" or "schedutil" are present

• Cleaned up and refactored.
    Added more convenient util functions.
    Also made it more pythonic, reduced subprocess calls, made it more modular

• Added support for setting turbo boost for AMD and Intel (intel_pstate and cpufreq driver)

• Tested on Intel and AMD machines and it works fine

  • It at least doesn't fail
  • performance/powersave is
  • turbo is switching on high CPU load.

• It needs more testing

@AdnanHodzic please, don't review it. Just tried it on amd and have issues.

[Red-Eyed]

@AdnanHodzic now I tested it on AMD and fixed all related errors.
Didn't test snap version, as I have POP! OS

[Red-Eyed]

I would suggest to "squash merge" as I did a lot of garbage commits that should not be displayed in the master :)

[AdnanHodzic]

I'll definitely squash it before merging, so no worries about how many commits you make :)

However, I have problem testing the changes:

git checkout -b "Red-Eyed-fix_\#17_amd" "master"
fatal: 'Red-Eyed-fix_\#17_amd' is not a valid branch name.
git checkout -b "Red-Eyed:fix_#17_amd" "master"
fatal: 'Red-Eyed:fix_#17_amd' is not a valid branch name.

Could you maybe change the branch name so it doesn't have # in it (which I think is the problem with bash)?

[Red-Eyed]

yep, 1 min

[Red-Eyed]

recreated #67

@AdnanHodzic thanks for mentioned me in Release Notes!
I would change description for AMD: acpitz -> k10temp

@AdnanHodzic thanks for mentioned me in Release Notes!

Of course! I had to find a way to thank you for the effort you put into this release :)

Not function whit AMD V1605B:

`$ sudo auto-cpufreq --live

Note: You can quit live mode by pressing "ctrl+c"
