hw/386: Add EPYC mode topology decoding functions
These functions add support for building EPYC mode topology given the smp details like numa nodes, cores, threads and sockets. The new apic id decoding is mostly similar to current apic id decoding except that it adds a new field node_id when numa configured. Removes all the hardcoded values. Subsequent patches will use these functions to build the topology. Following functions are added. apicid_llc_width_epyc apicid_llc_offset_epyc apicid_pkg_offset_epyc apicid_from_topo_ids_epyc x86_topo_ids_from_idx_epyc x86_topo_ids_from_apicid_epyc x86_apicid_from_cpu_idx_epyc The topology details are available in Processor Programming Reference (PPR) for AMD Family 17h Model 01h, Revision B1 Processors. The revision guides are available from the bugzilla Link below.
