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.
