pci romfiles: add property, add default to PCIDeviceInfo
This patch adds a romfile property to the pci bus. It allows to specify a romfile to load into the rom bar of the pci device. The default value comes from a new field in PCIDeviceInfo. The property allows to change the file and also to disable the rom loading using an empty string. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
