Make Logitech diNovo edge touchpad work as a mouse (as intended).
Mouse device shows multiple reports with the same usage, which makes
hid-input.c remap those instances of this usage to different events. As a
result, the actual GenericDesktop.X and .Y usages end up mapped to .Z and .RX
events, which prevents the mouse from working.
