USB 3.0 hub port status field has different bit positions from 2.0 hubs. Since U-Boot only understands the old version, translate the new one into the old one.
This is quite hairy. I'd rather see some protocol version agnostic flag field rather than patching the wPortStatus and co.
I am not sure how do do that in a clean way. If we return the raw 3.0 hub port status data, that means we need change lot of hub codes here and there to do different parsing.
Since we are going to add USB 3.0 hub support, this feature is only available with driver model USB.
