similar to: [PATCH v4 03/42] 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.

Provide helper functions that convert from/to LE for virtio devices that are not operating in legacy mode. We check for the VERSION_1 feature bit to determine that.
