[PATCH for-5.2] hw/null-machine: Add the kvm_type() hook for MIPS

[Huacai Chen <zltjiangshi@gmail.com>]

MIPS has two types of KVM: TE & VZ, and TE is the default type. Now,
libvirt uses a null-machine to detect the kvm capability. In the MIPS
case, it will return "KVM not supported" on a VZ platform by default.
So, add the kvm_type() hook to the null-machine.

This seems not a very good solution, but I cannot do it better now.
