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.
