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.
