k3-am642-sk.dts does not introduce any nodes with the said compatibles.

"ti,am64-usb" compatible is introduced by k3-am642-main.dtsi.
There is only one compatible introduced so there is nothing to do about
order here.

i.e.
        usbss0: cdns-usb@f900000 {
                compatible = "ti,am64-usb";
                reg = <0x00 0xf900000 0x00 0x100>;

What is the functional problem you are facing? Maybe then someone
can point you in the right direction.
