gpio@f0003000: 'gpio-controller' is a required property
    From schema: Documentation/devicetree/bindings/gpio/litex,gpio.yaml
    gpio@f0003000: '#gpio-cells' is a required property
    From schema: Documentation/devicetree/bindings/gpio/litex,gpio.yaml

Fix this by adding the missing properties.
