power: supply: max17042_battery: Use modern PM ops to clear up warning

When building for a platform that does not have power management, such
as s390, there is an unused function warning, as
max17042_suspend_soc_alerts() is only used in max17042_suspend(), which
is under a CONFIG_PM_SLEEP #ifdef.

  drivers/power/supply/max17042_battery.c:957:13: error: 'max17042_suspend_soc_alerts' defined but not used [-Werror=unused-function]
    957 | static void max17042_suspend_soc_alerts(struct max17042_chip *chip)
        |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~

Use the modern DEFINE_SIMPLE_DEV_PM_OPS(), which allows the compiler to
see the functions as used while allowing it to eliminate them as unused
during the optimization phase. Use pm_ptr() to allow the compiler to
drop max17042_pm_ops when there is no PM support.
