Subject: [PATCH mfd-next] mfd: max14577 and sec: add PM_SLEEP dependency to
 suspend/resume

Add CONFIG_PM_SLEEP dependency to suspend and resume functions of
max14577 MFD driver and sec-core.c code.

This fixes the warnings:
drivers/mfd/max14577.c:176:12: warning: ‘max14577_suspend’ defined but not used [-Wunused-function]
drivers/mfd/max14577.c:199:12: warning: ‘max14577_resume’ defined but not used [-Wunused-function]
drivers/mfd/sec-core.c:347:12: warning: ‘sec_pmic_suspend’ defined but not used [-Wunused-function]
drivers/mfd/sec-core.c:369:12: warning: ‘sec_pmic_resume’ defined but not used [-Wunused-function]
