PCI: of: Reduce missing non-prefetchable memory region to a warning
The pci-rcar-gen2 controller requires only a prefetchable memory region, and the error prevents using pci_parse_request_of_pci_ranges() for it. Let's reduce this to just a warning message so this function can be used for pci-rcar-gen2.
