USB: add quirks to XHCI

While XHCI is very generic some revisions of chipsets have problems.
On dwc3 <= 3.00a Port Disable does not seem to work so we need to not
enable it.
For that introduce quirks to xhci so that controllers can steer
certain features. I would hope that this is and remains the only one.

Obtained from: an old patch mainly debugging other problems
MFC after: 2 weeks
