Subject: vfio/igd: add Gemini Lake and Comet Lake device ids
X-Git-Tag: v10.0.0-rc0~106^2~12

vfio/igd: add Gemini Lake and Comet Lake device ids

Both Gemini Lake and Comet Lake are gen 9 devices. Many user reports
on internet shows legacy mode of igd passthrough works as qemu treats
them as gen 8 devices by default before e433f208973f ("vfio/igd:
return an invalid generation for unknown devices").
