Update cpufreq FFI callback signatures to use `c_int` from the `kernel::prelude`, rather than accessing it explicitly through `kernel::ffi::c_int`. Although these types are defined in the `ffi` crate, they are re-exported via `kernel::prelude`. This aligns with the Rust-for-Linux coding guidelines and ensures proper C ABI compatibility across platforms.

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.
