* Power off the board. This function may or may not be supported by a

* Input Parameters:
* status - Status information provided with the power off event.
*
* Returned Value:
* If this function returns, then it was not possible to power-off the
* board due to some constraints. The return value int this case is a
* board-specific reason for the failure to shutdown.
