If both CONFIG_SENSORS_AMS_PMU and CONFIG_SENSORS_AMS_I2C are unset,
there is an unused variable warning in the ams driver:
drivers/macintosh/ams/ams-core.c: In function 'ams_init':
drivers/macintosh/ams/ams-core.c:181:29: warning: unused variable 'np'
181 | struct device_node *np;
The driver needs at least one of the configs enabled in order to
actually function. So fix the compiler warning by ensuring at least one
of the configs is enabled.
