hw/mips: Implement the kvm_type() hook in MachineClass
MIPS has two types of KVM: TE & VZ, and TE is the default type. Now we
can't create a VZ guest in QEMU because it lacks the kvm_type() hook in
MachineClass. This patch add the the kvm_type() hook to support both of
the two types.
[AM: Added "if defined" guards.]

hw/intc: Add Loongson LIOINTC support
Loongson-3 has an integrated liointc (Local I/O Interrupt Controller).
It is similar to Goldfish interrupt controller, but more powerful (e.g.,
it can route external interrupt to multi-cores).
Documents about Loongson-3's liointc:
1, https://wiki.godson.ac.cn/ip_block:liointc;
2, The "I/O中断" section of Loongson-3's user mannual, part 1.
