Retrieve device properties from EFI on Macs before ExitBootServices is
called and assign them to devices (patch [2/3]). 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.
