Various improvements from t-hash (updated by me)

    + Improve xhci_configure_endpoint().
        + Split off maxburst and interval calculation.
            + Start interval calculation with 10, not 11.
            + Put correct maxburst value.
        + Split off constructing endpoint context.
    + Improve xhci_event_transfer()
        + Remove case of unlikely completion codes I added.
    + Clear xr_cookies too when xhci_set_dequeue() clears xr_trb.
    + Return USBD_NO_ADDR if xhci_address_device fails with
      XHCI_TRB_ERROR_NO_SLOTS.
    + Add aprint_debug xhci capability registers.
    + Add & update comments.

I checked HCCPARAMS1 against version 1.1 of the XHCI specification.  Not
sure of previous version formats
