Gen12 removes the target-cache and age fields from the private PAT because MOCS now have the capability to set these itself. Only memory-type field should be programmed in the ppat, the reminded bits are reserved. Since now there are only 4 possible combinations, we could set only 4 PPAT and leave the reminded 4 as UC, but I left them as WB as we used to have before. Also these registers have been relocated to the 0x4800-0x481c range.
