Add device tree binding for the board (micro)controller on Ten64 family
boards[1].
The schema is simple and is (presently) only consumed by U-Boot, but it
is possible nvmem, watchdog and other features could be described in
the future, as well as extension to future Traverse boards.

The Kontron SMARC-sAM67 module features an on-board house keeping uC.
It's designed to be compatible with the older on-board CPLD used on the
SMARC-sAL28 board. To be prepared for any board specific quirks, add a
specific compatible.

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.

Add binding for the EC found in the Thinkpad T14s Gen6 Snapdragon,
which is based on the Qualcomm X1 Elite. Some of the system LEDs
and extra keys are only accessible via the EC.
