[PATCH] drivers/rtc/rtc-cmos.c: fix compilation warning when !CONFIG_PM_SLEEP

[PATCH] drivers/rtc/rtc-cmos.c: fix compilation warning when !CONFIG_PM_SLEEP

[Mika Westerberg]

CONFIG_PM will be set also if only CONFIG_PM_RUNTIME is set which causes
the compiler to emit following warning:

drivers/rtc/rtc-cmos.c:845:12: warning: ‘cmos_resume’ defined but not used [-Wunused-function]

Fix this by using CONFIG_PM_SLEEP instead of CONFIG_PM and removing it from
the driver pm ops as this has been taken care by SIMPLE_DEV_PM_OPS()
already.
