of/address: Add of_range_to_resource() helper
A few users need to convert a specific "ranges" entry into a struct
resource. Add a helper to similar to of_address_to_resource(). The
existing of_pci_range_to_resource() helper isn't really PCI specific,
so it can be used with the CONFIG_PCI check dropped.
