wm4 9b5a7241e8 input: remove Linux joystick support
Why did this exist in the first place? Other than being completely
useless, this even caused some regressions in the past. For example,
there was the case of a laptop exposing its accelerometer as joystick
device, which led to extremely fun things due to the default mappings of
axis movement being mapped to seeking.

I suppose those who really want to use their joystick to control a media
player (???) can configure it as mouse device or so.
