platform/x86/intel-uncore-freq: Add attributes to show die_id

Browse source

For domains with agents to control cores (compute dies) show matching
Linux CPU die ID. Linux CPU ID is a logical die ID, so this may not match
physical die ID or domain_id. So, a mapping is required to get Linux CPU
die ID. This attribute is only presented when CPUID enumerates die ids.

This attribute can be used by orchestration software like Kubernetes to
target specific dies for uncore frequency control.
