PCI: remove unused resource assignment in pci_read_bridge_bases()

This cleanup removes the resource assignment in pci_read_bridge_bases()
since it has taken care by pci_alloc_child_bus() when allocating the bus:

        /* Set up default resource pointers and names.. */
        for (i = 0; i < PCI_BRIDGE_RES_NUM; i++) {
                child->resource[i] = &bridge->resource[PCI_BRIDGE_RESOURCES+i];
                child->resource[i]->name = child->name;
        }
