Subject: perf/x86/intel/uncore: Add Sapphire Rapids server MDF support
Git-commit: 0d771caf728436d9ebc2cd1d50bed71685bfe7d8
Patch-mainline: v5.15-rc1
References: jsc#SLE-18939
The MDF subsystem is a new IP built to support the new Intel Xeon
architecture that bridges multiple dies with a embedded bridge system.
The layout of the control registers for a MDF uncore unit is similar to
a IRP uncore unit.
