iio: adc: axp288_adc: convert probe to full device-managed
This change converts the probe of this driver to use device-managed
functions only, which means that the remove hook can be removed.
The remove hook has only 2 calls to iio_device_unregister() and
iio_map_array_unregister(). Both these can now be done via devm register
functions, now that there's also a devm_iio_map_array_register() function.
The platform_set_drvdata() can also be removed now.
This change also removes the error print for when the iio_device_register()
call fails. This isn't required now.
