Michael Hennerich 30e1bd0d3e iio: dac: ad5593r: Fix i2c read protocol requirements
commit 558a25f903b4af6361b7fbeea08a6446a0745653 upstream.

For reliable operation across the full range of supported
interface rates, the AD5593R needs a STOP condition between
address write, and data read (like show in the datasheet Figure 40)
so in turn i2c_smbus_read_word_swapped cannot be used.

While at it, a simple helper was added to make the code simpler.

Fixes: 56ca9db862 ("iio: dac: Add support for the AD5592R/AD5593R ADCs/DACs")
