PM runtime is enabled for the parent i2c device, but it is disabled for the iio child device and remains so in this driver. But as the child sysfs PM directory is created by default by iio_device_register => cdev_device_add => dpm_sysfs_add it doesn't bring any value exposing it since it won't give any usable data for the user. Tell dpm_sysfs to not create the PM directory for the iio device.
