xhci: define the new default speed ID for SuperSpeedPlus used by xhci hw
USB 3.1 capable xhci controllers use a new default speed ID "5" in the
PORTSC register to represent a 10Gbps connection speed of a SuperSpeedPlus
device
Make sure the xhci driver can handle the returned SuperSpeedPlus speed ID
properly
