udev: add a model-quirks callout
Some model-specific information isn't available through udev properties. This
callout is used to query the device directly and set a property that we can
then match on for the hwdb entries.
This is geared for Elantech and ALPS touchpads where the firmware version is
the interesting bit. The udev rule is added already to match on that, note
that the callout doesn't do anything at this point. The various
touchpad-related things will be added separately.
