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.

There were several files converted to yaml, but the .txt file
is still referenced somewhere else.
Update the references for them to point to the right file.

The example for the CrOS EC PWM is incomplete and now generates a dtc
warning:
Documentation/devicetree/bindings/pwm/google,cros-ec-pwm.example.dts:17.11-23.11:
Warning (unit_address_vs_reg): /example-0/cros-ec@0: node has a unit name, but no reg or ranges property
Fixing this results in more warnings as a parent spi node is needed as
well.

Convert the binding file google,cros-ec-pwm.txt to YAML format.
This was tested and verified on ARM64 with:
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/pwm/google,cros-ec-pwm.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/pwm/google,cros-ec-pwm.yaml
