Subject: [PATCH] conf: Introduce parser, formatter for uid and fid
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch introduces new XML parser/formatter functions. Uid is
16-bit and non-zero. Fid is 32-bit. They are the two attributes of zpci
which is introduced as PCI address element. Zpci element is parsed and
formatted along with PCI address. And add the related test cases.
