AD5311R is a single channel DAC with 10-bit precision and i2c interface.
The device includes a 2.5V internal reference which is enabled by default.
This device is similar to AD5691R/AD5692R/AD5693/AD5693R, the only
difference is that it has 10-bit precision.

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.
