[PATCH 0/3] platform/surface: Move Surface Aggregator client hubs to their own modules

[Maximilian Luz]

This series moves the Surface Aggregator client device hubs from the
Surface Aggregator registry to their own modules. While, at the moment,
client device hubs are exclusively instantiated by the registry platform
hub driver, this will change in the future. In particular, with the
introduction of DT/OF support, which is required for the Surface Pro X.
Therefore, this series also slightly restructures the functions used for
software-node-based device instantiation, essentially acting as
preparation for that.

In addition, this series follows-up "platform/surface: aggregator: Add
support for client hot-removal" and further removes some code
duplication by consolidating more parts of the hub drivers. While at it,
also ensure proper handling of firmware node lifetimes and update the
copyright year of various files.
