This will be used in subsequent CLs to support PD software sync. For now, only devidx=0 is used. This changes the external vboot API, so must be checked in at the same time as changes to the u-boot and depthcharge implementations. For now, those implementations should simply check if devidx=0 and fail if it's not.
