[PATCH -next] regulator: rk808: Fix sparse non static symbol warnings

[weiyj_lk]

From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>

Fixes the following sparse warnings:

drivers/regulator/rk808-regulator.c:100:5: warning:
 symbol 'rk808_set_suspend_voltage' was not declared. Should it be static?
drivers/regulator/rk808-regulator.c:115:5: warning:
 symbol 'rk808_set_suspend_enable' was not declared. Should it be static?
drivers/regulator/rk808-regulator.c:126:5: warning:
 symbol 'rk808_set_suspend_disable' was not declared. Should it be static?
