vfio/igd: Handle x-igd-opregion option in config quirk

Browse source 
Both enable OpRegion option (x-igd-opregion) and legacy mode require
setting up OpRegion copy for IGD devices. As the config quirk no longer
depends on legacy mode, we can now handle x-igd-opregion option there
instead of in vfio_realize.
