[PATCH AUTOSEL 4.19 051/209] x86/PCI: Apply VMD's AERSID fixup generically

From: Jon Derrick <jonathan.derrick@intel.com>

[ Upstream commit 4f475e8e0a6d4f5d430350d1f74f7e4899fb1692 ]

A root port Device ID changed between simulation and production. Rather
than match Device IDs which may not be future-proof if left unmaintained,
match all root ports which exist in a VMD domain.
