This is used for VirtioPCIProxy types so that --device virtio-blk-pci has properties of its embedded --device virtio-blk-device object. Currently this function is implemented using qdev properties. Change the function to use QOM object class properties instead. This works because qdev properties create QOM object class properties, but it also catches any QOM object class-only properties that have no qdev properties. This change ensures that properties of devices are shown with --device foo,\? even if they are QOM object class properties.
