Subject: [PATCH 3/3] iio: adc: ad7923: register device with
 devm_iio_device_register

Registers the device using the devm variant.
This is the final step of converting the ad7923 to only use devm routines,
meaning that the ad7923_remove() function is no longer needed to release
resources on device detach.
