PCI: of_property: Assign PCI instead of CPU bus address to dynamic PCI nodes

Browse source

commit 5e316d34b5 upstream.

When populating "ranges" property for a PCI bridge or endpoint,
of_pci_prop_ranges() incorrectly uses the CPU address of the resource.  In
such PCI nodes, the window should instead be in PCI address space. Call
pci_bus_address() on the resource in order to obtain the PCI bus address.
