This will result in the functions always being included, even if
PM_SLEEP is off...

...because they will always be used by the definition of
snvs_rtc_pm_ops here.
In order for this to work, SIMPLE_DEV_PM_OPS() needs to be used,
so that the dev_pm_ops struct is empty when PM is off and the functions
don't get referenced. See: https://lkml.org/lkml/2019/1/17/376
