Subject: [PATCH 1/2] perf/x86/intel/uncore: Add more IMC PCI IDs for KabyLake
 and CoffeeLake CPUs

KabyLake and CoffeeLake CPUs have the same client uncore events as SkyLake.

Add the PCI IDs for the KabyLake Y, U, S processor lines and CoffeeLake U,
H, S processor lines.

Subject: [PATCH 2/2] perf/x86/intel/uncore: Support CoffeeLake 8th CBOX

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.
