hw/loongarch/virt: Add CPU topology support
Add topological relationships for Loongarch VCPU and initialize topology member variables. On LoongArch system there is socket/core/thread topo information, physical CPU id is calculated from CPU topo, every topo sub-field is aligned by power of 2. So it is different from logical cpu index. Co-developed-by: Xianglai Li <lixianglai@loongson.cn> Signed-off-by: Bibo Mao <maobibo@loongson.cn>
