x86/cacheinfo: Refactor CPUID leaf 0x2 cache descriptor lookup

Extract the cache descriptor lookup logic out of the leaf 0x2 parsing
code and into a dedicated function.  This disentangles such lookup from
the deeply nested leaf 0x2 parsing loop.

Remove the cache table termination entry, as it is no longer needed
after the ARRAY_SIZE()-based lookup.

[ darwi: Move refactoring logic into this separate commit + commit log.
	 Remove the cache table termination entry. ]
