[PATCH slof v2] pci-properties: Remove redundant call to device-type

[Alexey Kardashevskiy <aik@ozlabs.ru>]

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.
