staging: iio: cdc: ad7746: Break up use of chan->address and use FIELD_PREP etc

Browse source

Instead of encoding several different fields into chan->address use
an indirection to a separate per channel structure where the various
fields can be expressed in a more readable form.  This also allows
the register values to be constructed at runtime using FIELD_PREP().

Drop the now redundant _SHIFT macros.
