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`.
