[PATCH v3 6/6] iio: adc: bcm_iproc_adc: use devm_iio_device_register()

From: Mohammad Shahid <redacted> Use devm_iio_device_register() to automatically unregister the IIO device when the device is detached. This removes the manual iio_device_unregister() call and makes the iproc_adc_remove() callback unnecessary.
