rG8f892e9bee33: XHCI: clear warm and port reset
Summary

It seems we do not clear UPS_C_BH_PORT_RESET and UPS_C_PORT_RESET
conditions after warm or port reset. Add that code.

Obtained from: an older patch used for debugging

I have to admit I no longer have a recollection when I did this and what was the cause.
I figured I put it up for review so you can have a look before I'll lose it.

You might want to check if the device is super-speed before doing this.

might -> must, because this bit has different meaning for USB 2.0 !
