x86/cacheinfo: Introduce cpuid_amd_hygon_has_l3_cache()
Multiple code paths at cacheinfo.c and amd_nb.c check for AMD/Hygon CPUs
L3 cache presensce by directly checking leaf 0x80000006 EDX output.
Extract that logic into its own function. While at it, rework the
AMD/Hygon LLC topology ID caclculation comments for clarity.
