I am not an expert here, I do not know what the best practice is.
But, I would do following:

/ {
(...)

    my_device: my_device@0 {
        default-device = <&default_device>;
    }

(...)
};

&i2c1 {
    default_device: default_device@75 {
        compatible = "some-name-never-mind";
        reg = <0x75>;
    };
};

Cheers,
Ezra.
