I don't see how this can be a patch on its own.

The only way to be able to use a patch for each driver would be to
keep the original grant-, event- and xenbus-interfaces and add the
new ones taking xenhost * with a new name. The original interfaces
could then use xenhost_default and you can switch them to the new
interfaces one by one. The last patch could then remove the old
interfaces when there is no user left.
