powerpc: move hmi.c to arch/powerpc/kvm/
hmi.c functions are unused unless sibling_subcore_state is nonzero, and
that in turn happens only if KVM is in use. So move the code to
arch/powerpc/kvm/, putting it under CONFIG_KVM_BOOK3S_HV_POSSIBLE
rather than CONFIG_PPC_BOOK3S_64. The sibling_subcore_state is also
included in struct paca_struct only if KVM is supported by the kernel.
