Subject: [PATCH 00/18] thunderbolt: Align with USB4 inter-domain and DROM specs

Hi all,

The latest USB4 spec [1] also includes inter-domain (peer-to-peer, XDomain)
and DROM (per-device ROM) specs. There are sligth differences between what
the driver is doing now and what the spec say so this series tries to align
the driver(s) with that. We also improve the "service" stack so that it is
possible to run multiple DMA tunnels over a single XDomain connection, and
update the two existing service drivers accordingly.

We also decrease the control channel timeout when software based connection
manager is used.

The USB4 DROM spec adds a new product descriptor that includes the device
and IDs instead of the generic entries in the Thunderbotl 1-3 DROMs. This
series updates the driver to parse this descriptor too.
