Intel-SIG: commit 6795e558 perf/x86/intel: Add Emerald Rapids
Backport for adding EMR PMU support to OLK-5.10 kernel.

-------------------------------------

From core PMU's perspective, Emerald Rapids is the same as the Sapphire
Rapids. The only difference is the event list, which will be
supported in the perf tool later.
