SF: Scheduler: touch boost whenever possible

With the previous commit entering idle aggressively, it is important that
touch boost works well.

Since there are valid cases where we would want touch boost to work when
there are no layers detected (e.g., notification panel pull down if it
was not accounted for during the initial vote type set), change touch
boost to work regardless of layer's status.
