Subject: perf/x86/cstate: Add Raptor Lake support
Git-commit: 2da202aa1c38bfe8841611a3d339892eb5579e2b
Patch-mainline: v5.18-rc2
References: jsc#PED-828

Raptor Lake is Intel's successor to Alder lake. From the perspective of
Intel cstate residency counters, there is nothing changed compared with
Alder lake.

Share adl_cstates with Alder lake.
Update the comments for Raptor Lake.
