Subject: [PATCH V2 2/4] perf/x86/cstate: Add Raptor Lake support

From: Kan Liang <kan.liang@...ux.intel.com>

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.
