Currently the device paths don't match the dm tree. We should create a device path node per dm tree node.

This affects very few uclasses but adds a field to all of them. I think an event might be best for this. We can add an event spy in each of the affected uclasses.
This is supposed to be a call from the efi subsystem do get a DP for a given device. I am not sure how we could replace this with an event.
