[PATCH libinput 1/2] udev: drop the custom firmware detection code in favor of a modalias

This was overengineered. The separation between the model quirks file and the udev hwdb matches allowed for more complex firmware detection. Except we never used it anywhere but on ALPS and there we can, thankfully, just get it from the version number in the input_id field exposed in the modalias.
