I don't like samples as they rarely get built or tested. We seem to already
have kunit support for rust, wouldn't it make more sense to implement a kunit
module for rust GPIO abstractions? If we don't have provider abstractions, you
should be able to reuse gpio-sim as the GPIO controller for testing just by
instantiating simulated GPIO devices.
