[PATCH evdev] Devices configured as mice need REL_X/Y

[Peter Hutterer]

Some keyboards export scroll axes and any absolute axis possible in 11
dimensions. All these axes are mute, except possibly for the scroll wheels.

So if a device has a scroll axis, and we're configuring it as mouse, force
the x/y axes into existence. This stops the logspam complaining about not
enough axes on pointer movement after a xrandr change.

This may also be the fix for 47281 though it's likely more of a workaround
than a fix.
