virtio: add virtio 1.0 feature bit
Based on original patches by Rusty Russell, Thomas Huth
and Cornelia Huck.
Note: at this time, we do not negotiate this feature bit
in core, drivers have to declare VERSION_1 support explicitly.
For this reason we treat this bit as a device bit
and not as a transport bit for now.
After all drivers are converted, we will be able to
move VERSION_1 to core and drop it from all drivers.
