It doesn't make sense to copy values manually:
the only issue with getting headers from linux
seems to be dealing with linux/types, we
can easily fix that automatically while importing.

FYI this is what I propose instead of the recently
suggested
    virtio: uniform virtio device IDs
we can then rework existing code to include these headers.

Will automatically bring in goodies as they arrive in linux.

This doesn't yet import virtio ccw header,
that won't be hard to add later.
