To be able to factor out address asignment of memory devices, we will have to read (get_addr()) and write (set_addr()) the address. We cannot use properties for this purpose, as properties are device specific. E.g. while the address property for a DIMM is called "addr", it might be called differently (e.g. "phys_addr") for other devices. E.g. virtio based memory devices cannot use "addr" as that is already reserved and used for the virtio device address on the bus.
