iio:dac:ad5686: Move exports into IIO_AD5686 namespace

Note these are used in the related ad5696-i2c drivers as well as the
more obviously connected ad5686-spi driver.

In order to avoid unnecessary pollution of the global symbol namespace
move the common/library functions into a specific namespace and import
that into the various specific device drivers that use them.
