iio: st_sensors: remove all driver remove functions
At this point all ST driver remove functions do iio_device_unregister(). This change removes them from them and replaces all iio_device_register() with devm_iio_device_register(). This can be done in a single change relatively easy, since all these remove functions are define in st_sensors.h.
