arm64: dts: uniphier: Rename gpio-hog nodes

According to gpio-hog schema, should add the suffix "-hog" to the node
names including gpio-hog to fix the following warning.

  uniphier-ld11-ref.dtb: gpio@55000000: 'xirq0' does not match any of the regexes: '^.+-hog(-[0-9+)?$', 'pinctrl-[0-9]+'
      From schema: Documentation/devicetree/bindings/gpio/socionext,uniphier-gpio.yaml

This applies to the devicetre for LD11, LD20 and PXs3 SoCs.
