Description

PS/2 driver selection in common_features.mk was using old approach (PS2_USE_INT, PS2_USE_BUSYWAIT etc.).
This PR reworks this to use same approach as Serial or WS2812 drivers, so it also supports vendor drivers.

This PR is first stage of merging my PS/2 driver for RP2040, which uses PIO. The second PR will contain the driver itself, but requires this PR to work.

so it was reworked to current approach, inspired by Serial
and WS2812 driver selections.

One thing I would like you to add to this PR is the addition of the PS/2 driver selection to the data driven config mappings in https://github.com/qmk/qmk_firmware/blob/develop/data/mappings/info_rules.json#L33-L34 just like it has been done for the steno protocols. Thank you.

Hi @KarlK90 , I fixed one indentation mistake, and implemented PS2 driver selection to data driver config mappings as you suggested. Please, let me know if it looks good. Thanks 😊

@gamelaster Great job, works like a charm. While playing around with the changes I recognized that we should probably add the clock and data pins to the data driven mappings as well, so for a "simple" setup we don't need to touch config.h at all. I've attached the necessary changes as a patch -> clock_data_pin.diff.txt
