Subject: [PATCH 04/16] thunderbolt: Move thunderbolt domain structure to thunderbolt.h

From: Mika Westerberg <[email-masked]>
Date: Mon, 18 Sep 2017 18:30:37 +0300

These are needed by Thunderbolt services so move them to thunderbolt.h
to make sure they are available outside of drivers/thunderbolt.
