x86/cacheinfo: Use consolidated CPUID leaf 0x2 descriptor table

CPUID leaf 0x2 output is a stream of one-byte descriptors, each implying
certain details about the CPU's cache and TLB entries.

At previous commits, the mapping tables for such descriptors were merged
into one consolidated table.  The mapping was also transformed into a
hash lookup instead of a loop-based lookup for each descriptor.

Use the new consolidated table and its hash-based lookup through the
for_each_leaf_0x2_tlb_entry() accessor.  Remove the old cache-specific
mapping, cache_table[], as it is no longer used.
