tools/power/x86/intel-speed-select: Introduce TPMI interface support
TPMI (Topology Aware Register and PM Capsule Interface) creates a flexible, extendable and software-PCIe-driver-enumerable MMIO interface for PM features. SST feature is exposed via the TPMI interface on newer Xeon platforms. Kernel TPMI based SST driver provides a series of new IOCTLs for userspace to use. Introduce support for the platforms that do SST control via TPMI interface. Compared with previous platforms, Newer Xeons also supports multi-punit in a package/die, including cpu punit and non-cpu punit. These have already been handled in the generic code.
