Implement support of uncore frequency control via TPMI (Topology Aware Register and PM Capsule Interface). This driver provides the similar functionality as the current uncore frequency driver using MSRs. Previously I posted only 1/3 and got reviewed and addressed with this submission. The other two patches were links in the submission. But it is better that all three patches considered together. I know this is close to merge window for 6.4, so it is fine to differ.
