Added new buttonmap for PS4 controller (both v1 and v2)

[arucard21]

After updating my system, it seems like the PS4 (both v1 and v2) controllers are detected a bit differently. I created a new buttonmap for it, which I'm providing in this PR. It seems like both v1 and v2 are detected as the same type of controller now, so only 1 buttonmap is required.

I think this may be because I updated to the linux 4.11 kernel which now has support for the PS4v2 controller. In earlier kernel versions, the PS4v2 controller wasn't explicitly supported, it seemed to partially work because of the PS4v1 controller code.

Great, thanks for the button map. Can you map the remaining controller profiles? There's a bunch that will show up if you select "Get More".

[arucard21]

You mean the Playstation, SNES, etc. profiles? Should I create a new PR for that or just add it to this one?

This PR is fine

I added the profiles. Note that some of the controllers didn't really have an obvious mapping for all buttons (especially the 6-button genesis controller), so I just made something up. I don't know if this matches what you've done for the other controllers as it's not really easy to read from the buttonmap files.

The biggest deviation with the genesis controller is mapped like this:
A -> square
B -> X
C -> O
X -> triangle
Y -> L1
Z -> R1
If there's some standard/preferred mapping for these controllers, let me know and I'll map them again.

I manually emptied the <configuration> block now.

I actually noticed this before and remapped for the Kodi profile, but that didn't remove it so I thought it might be intended. Not sure when and how it got added.

Thanks. Looks good now.

Thanks for the button maps. They'll be included in my next round of test builds.

5 years later I noticed that my PS4 controller uses digital buttons instead of analog axes for the triggers. Improvement sent in #235
