Input: ALPS - fix TrackStick Y axis handling for SS5 hardware
A minus character was lost in commit 23fce365, causing the Y axis to be
inverted for SS5 TrackStick events. (Pushing the TrackStick up caused
the pointer to move down, and vice versa.) Restore the lost minus.
Fixes: 23fce365c6a2 ("Input: ALPS - clean up code for SS5 hardware")
