Arnd Bergmann 00f7f90c51 rtc: cmos: avoid unused function warning ...

A bug fix for the ACPI side of this driver caused a harmless
build warning:

drivers/rtc/rtc-cmos.c:1115:13: error: 'cmos_check_acpi_rtc_status' defined but not used [-Werror=unused-function]
 static void cmos_check_acpi_rtc_status(struct device *dev,

We can avoid the warning and simplify the driver at the same time
by removing the #ifdef for CONFIG_PM and rely on the SIMPLE_DEV_PM_OPS()
to set everything up correctly. cmos_resume() has to get marked
as __maybe_unused so we don't introduce another warning, and
the two variants of cmos_poweroff() can get merged into one using
an IS_ENABLED() check.
