Virtio memory devices rely on PCI BARs to expose the contents of memory.
Because of this they cannot be used with virtio-mmio or virtio-ccw. In fact
the code that is common to virtio-mem and virtio-pmem, which is in
hw/virtio/virtio-md-pci.c, is only included if CONFIG_VIRTIO_PCI is
set. Reproduce the same condition in the Kconfig file.
Without this patch it is possible to create a configuration with
CONFIG_VIRTIO_PCI=n and CONFIG_VIRTIO_MEM=y, but that causes a
compilation failure.
