dt-bindings: pinctrl: mediatek: mt8183: Allow gpio-line-names

Add support for the 'gpio-line-names' property in the MT8183 pinctrl
binding.
This allows naming the GPIOs, which is already done in several
device trees (e.g. mt8183-kukui-jacuzzi.dtsi, mt8183-kukui-kakadu.dtsi,
mt8183-kukui-krane.dtsi), but was previously generating DT schema
warnings.
