The devices that properties pertain to are encoded as EFI Device Paths, so add a parser for these (patch [1/3]). As a first use case, amend the Thunderbolt driver to take advantage of the Device ROM supplied by EFI (patch [3/3]). Changes since v1: - Previously there were two separate patches for retrieving properties and assigning them to devices. These are now squashed together in patch [2/3]. (Requested by Matt Fleming.) - The version of the EFI properties protocol as well as the properties payload is now checked. - Applied a bit of polish all over.
