rust: platform: add basic platform device / driver abstractions Implement the basic platform bus abstractions required to write a basic platform driver. This includes the following data structures: The `platform::Driver` trait represents the interface to the driver and provides `platform::Driver::probe` for the driver to implement. The `platform::Device` abstraction represents a `struct platform_device`. In order to provide the platform bus specific parts to a generic `driver::Registration` the `driver::RegistrationOps` trait is implemented by `platform::Adapter`.

rust: driver: address soundness issue in `RegistrationOps` The `RegistrationOps` trait holds some obligations to the caller and implementers. While being documented, the trait and the corresponding functions haven't been marked as unsafe. Hence, markt the trait and functions unsafe and add the corresponding safety comments. This patch does not include any fuctional changes.
