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.
