Looking at  arch/arm/boot/dts/imx6q-bx50v3.dtsi from Linux, which
includes arch/arm/boot/dts/imx6q-bx50v3.dtsi, the wdog definition is
present:

&wdog1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_wdog>;
fsl,ext-reset-output;
};

So it would be better just use the same bindings in U-Boot without the
need of deviating the device tree.
