PCI: Move DT resource setup into devm_pci_alloc_host_bridge()
Now that pci_parse_request_of_pci_ranges() callers just setup pci_host_bridge.windows and dma_ranges directly and don't need the bus range returned, we can just initialize them when allocating the pci_host_bridge struct. With this, pci_parse_request_of_pci_ranges() becomes a static function.
