Apicid calculation depends on knowing the total number of numa nodes
for EPYC cpu models. Right now, we are calculating the arch_id while
parsing the numa(parse_numa). At this time, it is not known how many
total numa nodes are configured in the system.
Move the arch_id inside x86_cpus_init. At this time smp parse is already
completed and numa node information is available.
