Thanks...  it always seemed a little odd that I would have to disable
those...  I just tested that and it worked too.  So a smaller overlay
for an RPI2 would look like this:

/dts-v1/;

/ {
        compatible = "brcm,bcm2836";

        fragment@0 {
                target-path = "/soc/i2c@7e804000";

                __overlay__ {
                        status = "okay";
                        #address-cells = <0x01>;
                        #size-cells = <0x00>;
                        clock-frequency = <0x61a80>;

                        dsrtc@68 {
                                compatible = "dallas,ds1307";
                                reg = <0x68>;
                        };
                };
        };
};
