vfio/igd: Remove generation limitation for IGD passthrough
Starting from Intel Core Ultra Series (Meteor Lake), Data Stolen Memory
has became a part of LMEMBAR (MMIO BAR2) [1][2], meaning that BDSM and
GGC register quirks are no longer needed on these platforms.
To support Meteor/Arrow/Lunar Lake and future IGD devices, remove the
generation limitation in IGD passthrough, and apply BDSM and GGC quirks
only to known Gen6-12 devices.
