gblues 4555481863 WIIU: Fix touchscreen mouse emulation
== DETAILS
The way the mouse emulation worked was to simply return a 3rd axis from the
gamepad, which the polling code updates with the touch state in real time.

Well, the code that figures out if it's a positive or negative axis was
failing because it didn't see that 3rd axis as valid. So, I added values
which allow it to be seen as valid, and voila! the touch screen input
works again.

== TESTING
Tested locally using "Beneath a Steel Sky" in ScummVM.
