net/virtio: support Virtio link speed feature

This patch adds a support of VIRTIO_NET_F_SPEED_DUPLEX feature
for virtio driver.

There are two ways to specify speed of the link:
   'speed' devarg
   negotiate speed from qemu via VIRTIO_NET_F_SPEED_DUPLEX
The highest priority is devarg. If devarg is not specified,
drivers tries to negotiate it from qemu.
