[PATCH AUTOSEL 6.1 21/49] thermal: intel: intel_pch: Add support for Wellsburg PCH

From: Tim Zimmermann <tim@linux4.de>

[ Upstream commit 40dc1929089fc844ea06d9f8bdb6211ed4517c2e ]

Add the PCI ID for the Wellsburg C610 series chipset PCH.

The driver can read the temperature from the Wellsburg PCH with only
the PCI ID added and no other modifications.
