MIPS: Retire kvm paravirt

paravirt machine was introduced for Cavium's partial virtualization technology, however, it's host side support and QEMU support never landed in upstream. As Cavium was acquired by Marvel and they have no intention to maintain their MIPS product line, also paravirt is unlikely to be utilized by community users, it's time to retire it if nobody steps in to maintain it.
