iio: meter: ina3221: add dt binding header for iio channel support
Update the INA3221x DT binding documents and add dt-binding header to use
the macro from DTS file.
The updates details how it can be instantiated as iio channels and client
driver use this from DT node for measuring different parameters of different
channels. It also details the index for different signal monitor which
is require for iio channel consumer interface.
