platform/x86/intel: power-domains: Add interface to get Linux die ID
The die ID in the Linux topology sysfs is a logical identifier that differs from the one presented in CPUID leaf 0x1F or via MSR 0x54. Introduce an interface that returns the Linux CPU die ID based on a given package ID and power domain ID. This mapping is stored during the CPU online callback in an array.
