[v4,33/35] acpi/bus: Remove installing/removing notify handlers from probe/remove

Commit Message

Wilczynski, Michal June 1, 2023, 1:21 p.m. UTC

Remove installing/removing .notify callback handlers, to prepare for
notify callback removal.

Remove logic calling .remove callback, as .add should be expected to
clean after itself in case of the failure, and event handler
installation was moved to .add in all drivers already.
