Rust native atomics are not allowed to use in kernel due to the mismatch
of memory model with Linux kernel memory model, hence remove the usage
of Rust native atomics in debufs.

Adds a new sample driver that demonstrates the debugfs APIs.
The driver creates a directory in debugfs and populates it with a few
files:
- A read-only file that displays a fwnode property.
- A read-write file that exposes an atomic counter.
- A read-write file that exposes a custom struct.
This sample serves as a basic example of how to use the `debugfs::Dir`
and `debugfs::File` APIs to create and manage debugfs entries.
