Subject: [PATCH AUTOSEL 6.4 17/40] thunderbolt: Add Intel Barlow Ridge PCI ID

From: Mika Westerberg <mika.westerberg@...ux.intel.com>

[ Upstream commit 6f14a210661ce03988ef4ed3c8402037c8e06539 ]

Intel Barlow Ridge is the first USB4 v2 controller from Intel. The
controller exposes standard USB4 PCI class ID in typical configurations,
however there is a way to configure it so that it uses a special class
ID to allow using s different driver than the Windows inbox one. For
this reason add the Barlow Ridge PCI ID to the Linux driver too so that
the driver can attach regardless of the class ID.
