Since patch ("virtio-pci: introduce modern device module") got added it
is not possible to boot a defconfig kernel in qemu with a virtio pci
device. Add CONFIG_VIRTIO_PCI_MODERN=y fragment makes the kernel able
to boot.

Hi:
Based on the discussion previously, the plan is to select
VIRTIO_PCI_MODERN, and document the module that select it must depend on
PCI.
I will post a patch soon.
Thanks
