Accessing device properties is currently done via methods on `Device` itself, using bindings to device_property_* functions. This is sufficient for the existing method property_present. However, it's not sufficient for other device properties we want to access. For example, iterating over child nodes of a device will yield a fwnode_handle. That's not a device, so it wouldn't be possible to read the properties of that child node. Thus, we need an abstraction over fwnode_handle and methods for reading its properties. Add a struct FwNode which abstracts over the C struct fwnode_handle. Implement its reference counting analogous to other Rust abstractions over reference-counted C structs. Subsequent patches will add functionality to access FwNode and read properties with it.
