Only map x and y to axes 0 and 1
The Logitech G600 has one device with all axes north of ABS_MISC. The current
code assigns ABS_MISC as first axis to map to axis 0, i.e. x. On button press,
one node sends the BTN_LEFT but the other node sends an ABS_MISC with a 1 0
value. ABS_MISC is mapped to axis 0, this moves the pointer to (0, y) on
every button click.
Avoid this by simply mapping any axis other than x/y to at least axis 3, and
make sure we only override the MT 0/1 axes when we actually have MT axes.
