> That to imprecise. On older Intel platforms there are multiple controllers (EHCI, 2x UHCI).

That's fair. This is to support b/146506369, adding USB-PD information (like the port's power and data roles, etc.) in the SSDT under the EC object. But if we ever decide to use an SoC with more than one controller, this becomes brittle. Let me think a little more on this one.
