At the moment SLOF adds a "device_type" property automatically for every single PCI device based on its class even if there is no SLOF driver for such a device. OF1275 says that "device_type" is for implemented interfaces only. A side effect of this is virtio-balloon getting device_type=="memory" while it should not have. This removes automatic call to device-type from the common PCI code. Since now, we rely on existing SLOF PCI drivers to call device-type if needed. virtio-blk/net, e1000, ohci/ehci/xhci do this. virtio-scsi does not create the property for itself but disks on its bus do. virtio-ballon won't get the device_type property as there is no driver for it. While we are here, remove device-type from usb-mouse as well.
