Subject: [PATCH] dt-bindings: pinctrl: k230: fix child node name patterns

Rename child node name patterns to align with conventions.

    uart0-pins      =>   uart0-cfg
        uart0-cfg            uart0-pins

This avoids potential confusion and improves consistency with existing
bindings like sophgo,sg2042-pinctrl and starfive,jh7110-aon-pinctrl.

Fixes: 561f3e9d21a1 ("dt-bindings: pinctrl: Add support for canaan,k230 SoC")
