conf: Parse more of our nodedev XML
We were lacking tests that are checking for the completeness of our nodedev XMLs and also whether we output properly formatted ones. This patch adds parsing for the capability elements inside the <capability type='pci'> element. Also bunch of tests are added to show everything works properly.
