x86: Fix for cache computation on AMD legacy cpus.
Some legacy AMD CPUs and hypervisors have the _cpuid_ '0x8000_001D' set to Zero, thus resulting in zeroed-out computed cache values. This patch reintroduces the old way of cache computation as a fail-safe option to handle these exceptions. Fixed 'level4_cache_size' value through handle_amd(). Reviewed-by: Premachandra Mallappa <premachandra.mallappa@amd.com> Tested-by: Florian Weimer <fweimer@redhat.com> (cherry picked from commit dcad5c8578130dec7f35fd5b0885304b59f9f543)
