This adds binding, drivers and the DT support for the Huawei Matebook E Go (sc8280xp) Embedded Controller which is also found in Huawei Matebook E Go LTE (sc8180x), but I don't have the sc8180x one to perferform test, so this series enable support for sc8280xp variant only, this series provides the following features: - battery and charger information report - charging thresholds control - FN lock (An alternative method) - LID switch detection - Temperature sensors - USB Type-C altmode - USB Type-C PD(high power) Thanks to the work of Bjorn and Dmitry([1]), the work of Nikita([2]), writing a EC driver won't be suffering. This work refers a lot to their work, also, many other works. I mentioned them in the source file.
