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.
