ARM: 7466/1: disable interrupt before spinning endlessly
The CPU will endlessly spin at the end of machine_halt and
machine_restart calls. However, this will lead to a soft lockup
warning after about 20 seconds, if CONFIG_LOCKUP_DETECTOR is enabled,
as system timer is still alive.
Disable interrupt before going to spin endlessly, so that the lockup
warning will never be seen.
