Some OSes require that secondary cores not be initialized when they are booted (eg VxWorks). By default when U-Boot is compiled with the CONFIG_MP option all secondary cores are brought out of reset and held in spinloops. Setting the "mp_holdoff" environment variable to a non-null value will cause U-Boot to leave secondary cores in their default state.

While this may not be relevant to VxWorks, we should update the device tree's enable-method if mp_holdoff is set.
