Log Message:
Pull up following revision(s) (requested by martin in ticket #1032):
        sys/dev/pci/virtioreg.h: 1.13
        sys/dev/pci/virtio_pci.c: 1.44
Define the VIRTIO_F_ACCESS_PLATFORM, VIRTIO_F_RING_PACKED,
VIRTIO_F_ORDER_PLATFORM, and VIRTIO_F_SR_IOV feature bits.
--
On alpha and sparc64, use VirtIO 1.0 and VIRTIO_F_ACCESS_PLATFORM so
that DMA to PCI-attached VirtIO devices works properly.  This is needed
for Qemu to select the appropriate address space for PCI DMA.
