I can't find any documentation for this property, but it does appear to be
initialized by U-Boot:
/* We assume a cfg_addr not being set means we didn't setup the controller */
if ((hose == NULL) || (hose->cfg_addr == NULL)) {
fdt_del_node(blob, off);
} else {
bus_range[0] = 0;
bus_range[1] = hose->last_busno - hose->first_busno;
fdt_setprop(blob, off, "bus-range", &bus_range[0], 2*4);
fdt_pci_dma_ranges(blob, off, hose);
}
So I have no idea if it's required in the DTS.

Every other DTS sets this property to 33333333, and I don't see any code
in U-boot that fixes it up.
