In sun8i-r40 dts says gpio, should it be gpios? the same in the sun8i-v40 dts.

No, it is indeed "gpio", singular.
The exact name of properties is defined in the DT bindings, you should find the right document by searching for the compatible string in Documentation/devicetree/bindings.
In this case it's: Documentation/devicetree/bindings/regulator/fixed-regulator.yaml
Another (only indicative) source would be the actual driver implementation (in this case it turns out both names are accepted).
Cheers,
Andre.
