From: Angelo Dureghello <adureghello@baylibre.com>
Add new IIO calibconv_delay documentation.
The ad7606 implements a phase calibation feature, in nanoseconds.
Being this a time delay, using the conv_delay suffix.

+ Delay of start of conversion from common reference point shared

+ I.e., for the ad7606 ADC series, this value is intended as a
+ configurable time delay in seconds, to correct delay introduced
+ by an optional external filtering circuit.
