iio: magn/ak8974: avoid unused function warning
The ak8974_configure() function is used only from the PM code,
but that can be hidden when CONFIG_PM is disabled:
drivers/iio/magnetometer/ak8974.c:201:12: error: 'ak8974_configure' defined but not used [-Werror=unused-function]
This replaces the #ifdef with a __maybe_unused annotation, which
will work correctly in all configurations and avoid the warning,
as the compiler can now see where ak8974_configure is called from.
