[PATCH] cpufreq: rust: Use C FFI types in bios_limit_callback

[Abhinav Ananthu <abhinav.ogl@gmail.com>]

Update the bios_limit_callback function to use C FFI-compatible types
(kernel::ffi::c_int and kernel::ffi::c_uint) for its parameters and return
value. This ensures ABI compatibility with the corresponding C callback
signature.
