All gen 11 and 12 igd devices have 64 bit BDSM register at 0xC0 in its
config space, add them to the list to support igd passthrough on Alder/
Raptor/Rocket/Ice/Jasper Lake platforms.

Tested legacy mode of igd passthrough works properly on both linux and
windows guests with AlderLake-S GT1 (8086:4680).
