USB: xhci: Configure endpoint code refactoring.

Refactor out the code issue, wait for, and parse the event completion code
for a configure endpoint command.  Modify it to support the evaluate
context command, which has a very similar submission process.  Add
functions to copy parts of the output context into the input context
(which will be used in the evaluate context command).
