Rather than export a macro that delegates to `core::format_args`, simply
re-export `core::format_args` as `fmt` from the prelude. This exposes
clippy warnings which were previously obscured by this macro, such as:
warning: variables can be used directly in the `format!` string
--> ../drivers/cpufreq/rcpufreq_dt.rs:21:43
|
21 | let prop_name = CString::try_from_fmt(fmt!("{}-supply", name)).ok()?;
| ^^^^^^^^^^^^^^^^^^^^^^^
|
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#uninlined_format_args
= note: `-W clippy::uninlined-format-args` implied by `-W clippy::all`
= help: to override `-W clippy::all` add `#[allow(clippy::uninlined_format_args)]`
help: change this to
|
21 - let prop_name = CString::try_from_fmt(fmt!("{}-supply", name)).ok()?;
21 + let prop_name = CString::try_from_fmt(fmt!("{name}-supply")).ok()?;

Thus fix them in the same commit. This could possibly be fixed in two
stages, but the diff is small enough (outside of kernel/str.rs) that I
hope it can be taken in a single commit.

Use a consistent `# Examples` heading in rustdoc across the codebase.
Some modules previously used `## Examples` (even when they should be
available as top-level headers), while others used `# Example`, which
deviates from the preferred `# Examples` style.

In Rust 1.51.0, Clippy introduced the `ptr_as_ptr` lint [1]:
> Though `as` casts between raw pointers are not terrible,
> `pointer::cast` is safer because it cannot accidentally change the
> pointer's mutability, nor cast the pointer to other types like `usize`.
There are a few classes of changes required:
- Modules generated by bindgen are marked
`#[allow(clippy::ptr_as_ptr)]`.
- Inferred casts (` as _`) are replaced with `.cast()`.
- Ascribed casts (` as *... T`) are replaced with `.cast::<T>()`.
- Multistep casts from references (` as *const _ as *const T`) are
replaced with `core::ptr::from_ref(&x).cast()` with or without `::<T>`
according to the previous rules. The `core::ptr::from_ref` call is
required because `(x as *const _).cast::<T>()` results in inference
failure.
- Native literal C strings are replaced with `c_str!().as_char_ptr()`.
- `*mut *mut T as _` is replaced with `let *mut *const T = (*mut *mut
T)`.cast();` since pointer to pointer can be confusing.
Apply these changes and enable the lint -- no functional change
intended.

Move the `#[cfg(CONFIG_OF)]` attribute to the top of the documentation test
block and hide it. This applies the condition to the entire test and improves
readability.
Placing configuration flags like `CONFIG_OF` at the top serves as a clear
indicator of the conditions under which the example is valid, effectively
acting like configuration metadata for the example itself.
