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.
