[PATCH v4 6/6] iio: adc: bcm_iproc_adc: use devm-managed IIO device registration

[mdshahid03 at gmail.com]

From: Mohammad Shahid <mdshahid03 at gmail.com>

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.
