iio:mma8452: Use new iio_trigger_validate_own_device() helper
Use the new iio_trigger_validate_own_device() to verify that the trigger
can only be attached to the matching IIO device rather than using a custom
variant.
While the implementation of iio_trigger_validate_own_device() and the
custom variant and are not identical their behaviour is.
