iio:ad5446: Add support for I2C based DACs

Browse Source 
This patch adds support for I2C based single channel DACs to the ad5446
driver. Specifically AD5602, AD5612 and AD5622.

V1: from Lars-Peter Clausen <lars@metafoo.de>
V2: Split the device IDs into two enums and move them to the c file.

To compile this driver as a module, choose M here: the
module will be called ad5446.
