conf: node_device: fix mdev_types format and XML parsing code to match schema

Browse Source 
The nodedev schema defines that a mdev_types capability must have
one or more type elements. The XML parsing and the format allows to
accept and to write mdev_types capability without any type element.
This patches fixes this.
