USB: Add USB 3.0 roothub support to USB core.
Add USB 3.0 root hub descriptors. This is a kludge because I reused the old
USB 2.0 descriptors, instead of using the new USB 3.0 hub descriptors with
endpoint companion descriptors and other descriptors. I did this because I
wasn't ready to add USB 3.0 hub changes to khubd. For now, a USB 3.0 roothub
looks like a USB 2.0 roothub, with a higher speed.
USB 3.0 hubs have no transaction translator (TT).
Make USB core debugging handle super speed ports.
