Update all `unsafe extern "C"` callback functions in the cpufreq module to use `kernel::ffi` types (`c_int`, `c_uint`, etc.) instead of Rust-native types like `i32`, `u32`, or `usize`. This change ensures that all Rust callbacks have signatures that are ABI-compatible with their corresponding C counterparts, which is critical for FFI correctness and safety.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
