evdev: Clamp axis values to the 0.0-1.0 range
The values are expected to be in the 0.0-1.0 range (as indicated by the
comment), and other parts of Dolphin also expect it to be in that range
since the "full" axis has a -1.0 to 1.0 range. However, this is not
always the case and fvalue can end up being outside of the range. This
clamps fvalue to always be in the 0.0 and 1.0 range.
