On the parallel version, the current implementation is only compatible
with id tables and won't work with fw_nodes, this commit intends to fix
it.
Doing so required to declare ad7606_chip_info structures in the .h file
so to make them accessible to all the driver files that can set a
pointer to the corresponding chip as the driver data.
