commit e39b82f6cb0526c551d4651ba6d286b6b1f9e9c3 upstream. Clearwater Forest is based on the Darkmont Atom microarchitecture. >From the perspective of C-state residency profiling, it supports the same residency counters as Sierra Forest: CC1/CC6, PC2/PC6, and MC6. Please note that the C1E residency counter can only be read via PMT, not MSR. Therefore, tools relying on the perf_event framework cannot access the C1E residency.

Backport cstate PMU for CWF. Switch to new Intel CPU model defines and add SRF PC2 support at the same time.
Test:
Tested on SRF/GNR/CWF,
On SRF, perf event "cstate_pkg/c2-residency/" becomes available with this PR.
On CWF, perf events "cstate_core/c1-residency/ cstate_core/c6-residency/ cstate_module/c6-residency/ cstate_pkg/c2-residency/ cstate_pkg/c6-residency" become available with this PR.
On GNR, no regression found.
