[PATCH -next RESEND] mfd: ene-kb3930: Make symbol 'kb3930_power_off' static

['Wei Yongjun]

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

The sparse tool complains as follows:

drivers/mfd/ene-kb3930.c:36:15: warning:
 symbol 'kb3930_power_off' was not declared. Should it be static?

This symbol is not used outside of ene-kb3930.c, so this
commit marks it static.
