[PATCH v3 0/3] Apple device properties

[Lukas Wunner <lukas-JFq808J9C/izQB+pC5nmwQ@public.gmane.org>]

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 v2:

- Renamed get_device_by_efi_path() to efi_get_device_by_path() in
  patch [1/3]. (Matt Fleming)

- Support multiple instance device paths in patch [1/3]. (Peter Jones)

- Validate the size specified in the properties payload in patch [2/3].

- Other than that, just some minor polishing and rebasing.
