* A parent-less device should not crash dahdi:
- Access span->parent->dev instead of span->parent-dev.parent
in soem cases.
- Access span->parent->dev via new inline span_device()
- Use span_device() in all dahdi_dev_{dbg,info}()
* Allow low-level drivers to set their device name.
- Drivers that don't use this feature get the default name
based on the parent device name
- Parent-less devices which don't set their name, fails
to register with -EINVAL
