It seems that since commit b02d0ed6 ("xhci: Change hcd_priv into a
pointer.") we no longer use the container_of statement to get usb_hcd
from the xhci struct because we allocate it in the ->reset() callback.
However, we still allocate one at usb_create_hcd() time. So we have two
of them but we use only one.
Since commit f6ff0ac ("xhci: Register second xHCI roothub.") we
allocate a third one due the additional USB2 hub.
This patch removes the two struct xhci_hcd which are allocated at
usb_create_hcd() time and are not used.

This is totally untested but it kinda makes sense :)
