Subject: [PATCH 10/16] iio: ad7606: Fix type incompatibility with non-macro find_closest

The ad7606_oversampling_avail and ad7616_oversampling_avail arrays were
previously declared as unsigned int but used with find_closest(). With
find_closest() now implemented as a function taking signed int parameters
instead of a macro, passing unsigned arrays causes type incompatibility
errors. This patch changes the arrays type from unsigned int to int to
ensure compatibility with the function signature and prevent compilation
errors.
