[PULL 6/8] vfio/igd: add ID's for ElkhartLake and TigerLake

["Cédric Le Goater" <clg@redhat.com>]

From: Corvin Köhne <corvin.koehne@gmail.com>

ElkhartLake and TigerLake devices were tested in legacy mode with Linux
and Windows VMs. Both are working properly. It's likely that other Intel
GPUs of gen 11 and 12 like IceLake device are working too. However,
we're only adding known good devices for now.
