When CONFIG_XHCI_HCD_DEBUGGING is activated, the XHCI driver can dump device and input contexts to the console. The endpoint contexts in that dump are labeled "Endpoint N Context", where N is DCI - 1... this is very confusing, especially for people who are not that familiar with the XHCI specification. Let's change this to display the endpoint number and direction, which are much more commonly used concepts in USB (and map to XHCI DCIs 1-to-1).
