[libvirt] [RFC PATCH 09/11] nodedev: Format the mdev capability of the PCI parent device
This introduces a new nested capability element of type 'mdev' with the
resulting XML of the following format:
<device>
...
<capability type='pci'>
...
<capability type='mdev'>
<type id='vendor-supplied-id'>
<description>optional, raw, unstructured resource allocation data
</description>
<device_api>vfio-pci</device_api>
<available_instances>NUM</available_instances>
</type>
...
<type>
...
</type>
</capability>
</capability>
...
</device>
