The command "shutdown -h -H now" should shut the system down to the
OBP, however the machine was being powered off in the LDOM case.
In the LDOM case, the "reboot-command" variable must be set to
the string "noop" and then ldom_reboot() must be called.
This will make the OBP ignore the setting of "auto-boot?" after it
completes the reset. This causes the system to stop at the ok prompt.
