[PATCH V3] sched/rt, powerpc: Prepare for PREEMPT_RT

[Wang Qing]

PREEMPT_RT is a separate preemption model, CONFIG_PREEMPT will
 be disabled when CONFIG_PREEMPT_RT is enabled,  so we need
to add CONFIG_PREEMPT_RT output to __die().

Signed-off-by: Wang Qing <wangqing at vivo.com>

Changes in v3:
 - Fix typo issue.

Changes in v2:
 - Modify as Christophe suggested.
