xpedite1k: Move to X-ES vendor directory

The XPedite1000 is an X-ES product thus it can be put in board/xes along
with other X-ES boards.  Along with the move, the board was renamed to
XPedite1000 from XPedite1K to fit X-ES's standard naming convention.
Maintainership was also transfered to Peter Tyser.
