perf/x86/intel/cstate: Add Clearwater Forest support
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.
