Log Message:
Add needed framework for backend drivers.
As we want some control on the name the backend driver will have we
can't use autoconf(9) here. Instead backend drivers registers to
xenbus, which will call a create callback when a new device is there.
Backend devices won't have a "struct device" in xenbus, use a void pointer
instead.
