Input: xpad - fix inverted Y and RY axes

The commit ae91d10aab2762f81733e9194cb56eff99c8d808 inverted Y and RY
axes on xbox360 so that up is positive and down is negative.
This is wrong, as axes on game controllers have up as negative per
convention. Also, even xpad itself reports HAT0X with up as negative.

Fix that by inverting them again.

Also, according to http://bugzilla.kernel.org/show_bug.cgi?id=10337 the
original xbox controllers also have the Y and RY axes inverted.
Fix that by inverting them as well.
