Subject: pci: Move VMState registration/unregistration to QOM
 realize/unrealize
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use the realize and unrealize hooks to register and unregister
vmstate_pcibus respectively.

Relocate some stuff to avoid forward declarations.
