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: platform: add __rust_helper to helpers This is needed to inline these helpers into Rust code.

rust: platform: impl TryFrom<&Device> for &platform::Device Implement TryFrom<&device::Device> for &Device. This allows us to get a &platform::Device from a generic &Device in a safe way; the conversion fails if the device' bus type does not match with the platform bus type.
