Subject: [PATCH] Count REL_DIAL as a scrollwheel during EvdevProbe (#21457)

The Griffin Powermate only has a single axis (REL_DIAL). This axis is
posted as horizontal scroll wheel, so we need to ensure the scroll wheel
setup (including ensuring that enough buttons are available) is triggered
accordingly.
