[PATCH v3 16/17] i386: Use CPUCacheInfo.share_level to encode CPUID[0x8000001D].EAX[bits 25:14]

[Zhao Liu]

From: Zhao Liu <zhao1.liu@intel.com>

CPUID[0x8000001D].EAX[bits 25:14] is used to represent the cache
topology for amd CPUs.

After cache models have topology information, we can use
CPUCacheInfo.share_level to decide which topology level to be encoded
into CPUID[0x8000001D].EAX[bits 25:14].

Changes since v1:
 * Use cache->share_level as the parameter in
   max_processor_ids_for_cache().
