* [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 Co-authored-by: Drashna Jaelre <drashna@live.com> * Add PS/2 pins to data driven mappings Co-authored-by: Drashna Jaelre <drashna@live.com>
