platform/x86/intel-uncore-freq: tpmi: Provide cluster level control
The new generation of CPUs have granular control at a cluster level.
Each package/die can have multiple power domains, which further can
have multiple fabric clusters. The TPMI interface allows control at
fabric cluster level.
Use the updated uncore sysfs feature to expose controls at cluster
level. At each cluster level there is a control for maximum and minimum
uncore frequency. Also present current uncore frequency at a cluster
level.
