Subject: [PATCH 11/16] iio: mcp3564: Fix type incompatibility with non-macro find_closest

The mcp3564_oversampling_avail array was 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.
