    i386/cpu: Consolidate die-id validity in smp context
    
    The field die_id (default as 0) and has_die_id are introduced to X86CPU.
    Following the legacy smp check rules, the die_id validity is added to
    the same contexts as leagcy smp variables such as hmp_hotpluggable_cpus(),
    machine_set_cpu_numa_node(), cpu_slot_to_string() and pc_cpu_pre_plug().
