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.
