Subject: udev: Add support for device-tree-based model selection

This adds support for detecting input peripherals based on their name
and the device-tree model of the device they're used with.

This is mostly an equivalent to dmi-based model detection (e.g. on x86
devices) for device that use device-tree (e.g. on ARM devices).

Note that this requires systemd updates, see
https://github.com/systemd/systemd/pull/5837
