[PATCH v2 0/4] target/loongarch: Add host CPU type support

Host CPU model is basically the same with max CPU model, except Product
ID and CPU model name. With host CPU model, Product ID comes from
cpucfg0 on host machine and CPU model from /proc/cpuinfo, also some
CPUCFG bits which are irrelative with KVM hypervisor somes from host
machine.
