Subject: [PATCH v2] iio:dac:max517.c: Use devm_iio_device_register()

Use devm_iio_device_register() to avoid remove function and
drop explicit call to iio_device_unregister().

Signed-off-by: Mugilraj Dhavachelvan <dmugil2000@...il.com>

changes v1->v2:
	-As sugested by Alexandru removed i2c_set_clientdata() because the stored
	 data will be never used.
