iio: dac: ad5446: Add support for new AD5600 DAC 

[ Upstream commit 6376cbe549fffb378403cee78efd26b8a2c8e450 ]

The AD5600 is a single channel, 16-bit resolution, voltage output digital
to analog converter (DAC). The AD5600 uses a 3-wire SPI interface. It is
part of the AD5541 family of DACs.

The ad5446 IIO driver implements support for some of these DACs (in the
AD5441 family), so the change is a simple entry in this driver.
