[PATCH -next] cpuidle/pseries: Make symbol 'pseries_idle_driver' static

[Wei Yongjun]

The sparse tool complains as follows:

drivers/cpuidle/cpuidle-pseries.c:25:23: warning:
 symbol 'pseries_idle_driver' was not declared. Should it be static?
 
'pseries_idle_driver' is not used outside of this file, so marks
it static.
