MIPS: KVM: Move KVM_{GET,SET}_ONE_REG definitions into kvm_host.h 



Move the KVM_{GET,SET}_ONE_REG MIPS register id definitions out of
kvm_mips.c to kvm_host.h so that they can be shared between multiple
source files. This allows register access to be indirected depending on
the underlying implementation (trap & emulate or VZ).
