I think we can redefine only pad DAT3 in pinctrl_usdhc1_1_dat3cd, and
overwrite the DAT3 configuration in pinctrl_usdhc1_1 to save the
redundant data of other pads, something like the following.

pinctrl_usdhc1_1_dat3cd: usdhc1grp-3 {
	fsl,pins = <
		MX6QDL_PAD_SD1_DAT3__SD1_DATA3 0x13059
	>;
};

&usdhc1 {
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_usdhc1_1 &pinctrl_usdhc1_1_dat3cd>;
	...
	status = "okay";
};

Are you sure that this will always be the case?  This would assume that
the pinctrl entries are always processed sequentially.
