iio: st_sensors: remove reference to parent device object on st_sensor_data
The idea behind it, is that all devm_ calls in ST sensors are bound to the
parent device object.
However, the reference to that object is kept on both the st_sensor_data
struct and the IIO object parent (indio_dev->dev.parent).
This change only adds a bit consistency and uses the reference stored on
indio_dev->dev.parent, to enforce the assumption that all ST sensors' devm_
calls are bound to the same reference as the one store on st_sensor_data.
