Subject: [PATCH 2/4] iio: dac: ad5755: mark OF related data as maybe unused

The driver can be compile tested with !CONFIG_OF making certain data
unused (of_device_id is not used for device matching):

  drivers/iio/dac/ad5755.c:865:34: error: ‘ad5755_of_match’ defined but not used [-Werror=unused-const-variable=]
