Subject: [PATCH v3 6/7] staging: iio: ad5933: change attributes' ABI call

Change device attributes to use more suitable ABI functions when setting
and displaying AC output excitation voltage. It better complies with
device hardware since these attributes are used to manage DDS
peak-to-peak output voltage.
