Right now, we do hwdb lookups for keyboard:foobar, evdev:foobar and
now trackpoint:foobar, instead of a single lookup for evdev:foobar.

To me, it looks much easier if we have one generic evdev rule, which
searches the hwdb based on the input-modalias via
evdev:input:<modalias> and the legacy fallback,
evdev:name:<name>:<dmi>

Depending on what properties where found, we simply apply them to the
evdev node.

Thanks
