refactor(kscan): Match direct GPIO driver to matrix driver #1288

Merged

Rewrote the direct GPIO kscan driver to match the improvements made to the matrix driver in 82cb762 and f946dc6. It now uses the same debouncing system as the matrix driver.

Tested on my BDN9 rev2, with default debounce settings, as well as with:

                debounce-press-ms = <1>;
                debounce-release-ms = <5>;

applied, and it worked perfectly fine, no accidental duplicated presses, fast response time (subjectively).

Will peek at the code another time.

Any reason you moved this to APPLICATION instead of POST_KERNEL?

Copy/paste from the matrix driver, where it looks like it got switched from POST_KERNEL to APPLICATION in e448f2d. Do you remember why you did that there?
