intel_pstate: Add X86_FEATURE_APERFMPERF to cpu match parameters.

intel_pstate: Add X86_FEATURE_APERFMPERF to cpu match parameters.

commit 6cbd7ee10e2842a3d1f9b60abede1c8f3d1f1130 upstream.

KVM environments do not support APERF/MPERF MSRs. intel_pstate cannot
operate without these registers.

The previous validity checks in intel_pstate_msrs_not_valid() are
insufficent in nested KVMs.
