KVM: PPC: Always select KVM_VFIO, plus Makefile cleanup
As discussed recently on the kvm mailing list, David Gibson's intention in commit 178a78750212 ("vfio: Enable VFIO device for powerpc", 2016-02-01) was to have the KVM VFIO device built in on all powerpc platforms. This patch adds the "select KVM_VFIO" statement that makes this happen. Currently, arch/powerpc/kvm/Makefile doesn't include vfio.o for the 64-bit kvm module, because the list of objects doesn't use the $(common-objs-y) list. The reason it doesn't is because we don't necessarily want coalesced_mmio.o or emulate.o (for example if HV KVM is the only target), and common-objs-y includes both. Since this is confusing, this patch adjusts the definitions so that we now use $(common-objs-y) in the list for the 64-bit kvm.ko module, emulate.o is removed from common-objs-y and added in the places that need it, and the inclusion of coalesced_mmio.o now depends on CONFIG_KVM_MMIO.
