[PATCH v3 06/11] iio: dac: ad5686: remove redundant register definition

[Rodrigo Alencar via B4 Relay <devnull+rodrigo.alencar.analog.com@kernel.org>]

From: Rodrigo Alencar <rodrigo.alencar@analog.com>

AD5683_REGMAP and AD5693_REGMAP behave the same way in the common code,
and that is because they target single channel devices from the same
sub-family. There is no reason to separate them and it will make things
simpler when refactoring the chip info table.
