iio: adc: ti-ads8344: convert probe to device-managed
This change converts the driver to register via devm_iio_device_register().
The regulator disable is moved on a devm_add_action_or_reset() hook.
And the spi_set_drvdata() isn't required anymore.
And finally, the ads8344_remove() can be removed as well.
