Coffee Lake has 8 core products which has 8 Cboxes. The 8th CBOX is mapped into different MSR space. Increase the num_boxes to 8 to handle the new products. It will not impact the previous platforms, SkyLake, KabyLake and earlier CoffeeLake. Because the num_boxes will be recalculated in uncore_cpu_init and doesn't exceed the x86_max_cores. Introduce a new box flag bit to indicate the 8th CBOX.
