vfio/igd: add Alder/Raptor/Rocket/Ice/Jasper Lake device ids

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).
