PCI: Distribute available resources for root buses, too

Previously we distributed spare resources only upon hot-add, so if the
initial root bus scan found devices that had not been fully configured by
the BIOS, we allocated only enough resources to cover what was then
present. If some of those devices were hotplug bridges, we did not leave
any additional resource space for future expansion.

Distribute the available resources for root buses, too, to make this work
the same way as the normal hotplug case.
