Not sure it would really improve things that much. Subsystems/drivers
need to make additional configurations based upon whether this DT
property is set anyway.

Perhaps an option is to make this a part of the common input subsystem
helper functions instead? Other subsystems do this, but I am not sure
how feasible that would be in the input case.
