that shouldn't be an issue as kvm_ppc_register_host_cpu_type() demonstrates
(i.e. an additional class init at kvm/tcg init time),
so it might be some compat issue or just legacy approach why it
havn't been rewritten to class_init for x86 the way PPC does.
But Eduardo probably knows better if there is anything left that
prevents using class init there.
