[PATCH v5 next 7/7] iio: sca3000: manage device registration with devm helper

Convert the iio registration to use devm_* helpers so the probe no
longer needs a separate cleanup path and remove callback can also drop
the unregister. After this there is no need for having a remove
callback, so remote it.

No functional change intended.
