[Core] Rework PS/2 driver selection (#17892)
* [Core] Rework PS/2 driver selection

Enabling and selecting PS/2 driver was using old approach,
so it was reworked to current approach, inspired by Serial
and WS2812 driver selections.

* [Keyboard] Update keyboards using PS/2 to use new PS/2 driver selection

* [Docs] Update PS/2 documentation to use new PS/2 driver selection

* Fix indentation

* [Core] Add PS2 to data driver

* Fix oversight in property name

* Add PS/2 pins to data driven mappings
