[PATCH V4 05/16] perf/x86/intel/uncore: Add Sapphire Rapids server M2PCIe support

[kan . liang]

From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>

M2PCIe* blocks manage the interface between the mesh and each IIO stack.

The layout of the control registers for a M2PCIe uncore unit is similar
to a IRP uncore unit.
