Daniel Almeida 17e70f0c54 rust: platform: add irq accessors ...

These accessors can be used to retrieve a irq::Registration and
irq::ThreadedRegistration from a platform device by
index or name. Alternatively, drivers can retrieve an IrqRequest from a
bound platform device for later use.

These accessors ensure that only valid IRQ lines can ever be registered.
