iio: Update iio_channel_get_all and iio_channel_get_all_cb API
Pass device pointer instead of device name as parameter to iio_channel_get_all and iio_channel_get_all_cb. This will enable us to use OF information to retrieve consumer channel information. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
