The above makes sense as usb4 is only on dra74x and should not be even
available otherwise.

But let's keep the target-module@140000 here as it puts it in the right
location rather than directly on the ocp. Let's mark it with
status = "disabled" in dra7-l4.dtsi, and add a comment noting it's only
available on dra74x. So similar to what you had in your v1 patch, except
disabled.

Then the above change can be kept.

And in dra74x.dtsi just set it enabled then :)
Other than that looks good to me.
