Add const qualifier to struct ad8366_info ad8366_infos[]. This
is read-only data so it can be made const.

I looked into dropping use of the chip info array in this one, but
removing it isn't trivial. There are several switch statements that
are using the chip ID still. So we'll save that for another day.

Replying with the correct subject. I missed updating the prefix
from a copied commit message.

Should be `iio: amplifiers: ad8366:`

Fixed up and applied to the testing branch of iio.git on the
perhaps foolish basis "it's obviously correct" :)
