Move several embedded controller bindings (like ChromeOS EC, Gateworks System Controller and Kontron sl28cpld Board Management) to new subdirectory "embedded-controller" matching their purpose. An embedded controller (EC) is a discrete component that contains a microcontroller (i.e. a small CPU running a small firmware without operating system) mounted into a larger computer system running a fully fledged operating system that needs to utilize the embedded controller as part of its operation. So far the EC bindings were split between "mfd" and "platform" directory. MFD name comes from Linux, not hardware, and "platform" is a bit too generic. Rename Gateworks GSC and Huawei Gaokun filenames to match compatible, as preferred for bindings.

Surface devices use a standardized embedded controller to let the
|
|
operating system interface with various hardware functions. The
|
|
specific functionalities are modeled as subdevices and matched on
|
|
five levels: domain, category, target, instance and function.
