Driver only ever reports MT events and input_mt_init_slots() sets up
emulated axes already.  Clear the capabilities not generated directly
and move MT axes setup, so they are visible by input_mt_init_slots().

v5 applies cleanly to the current linux-next and everything working fine
on both Ubuntu 12.04 and 20.04! Thank you very much :)
