Effectivewise none, but to me it seems to be cleaner to set them once in
probe() instead of everytime reset() is called.

I admit I don't know the code flow good enough if reset() is called
more than once in the lifetime of a hcd device.

And as I said, it would allow doing the checks the patch adds for both
DT and !DT, not just DT only.
