[S390] kvm-s390: fix kconfig dependencies 



A user can create the Kconfig combination !VIRTUALIZATION, S390_GUEST
which results in the following warnings:

warning: (S390_GUEST) selects VIRTIO which has unmet direct dependencies (VIRTUALIZATION)
warning: (S390_GUEST && VIRTIO_PCI && VIRTIO_BALLOON) selects VIRTIO_RING which has unmet direct dependencies (VIRTUALIZATION && VIRTIO)
warning: (S390_GUEST) selects VIRTIO which has unmet direct dependencies (VIRTUALIZATION)
warning: (S390_GUEST && VIRTIO_PCI && VIRTIO_BALLOON) selects VIRTIO_RING which has unmet direct dependencies (VIRTUALIZATION && VIRTIO)

S390_GUEST has to select VIRTUALIZATION before selecting VIRTIO and
friends.
