spapr-pci: Stop providing assigned-addresses
QEMU does not allocate PCI resources (BARs) in any case - coldplug devices
are configured by the firmware and hotplug devices rely on the guest
system to do the assignment via the PCI rescan mechanism. Also in order
to create non empty "assigned-addresses", the device has to be enabled
(i.e. PCI_COMMAND needs the MMIO bit set) first as otherwise
io_regions[i].addr are -1, and devices are not enabled at this point.
This removes "assigned-addresses" and leaves it to those who actually
do resource allocation.
