Add device tree schema for the Realtek switch. Currently the only
supported feature is the syscon-reboot which is needed to be able to
reboot the board.

Notes:
Changes in v2:
- use filename that matches the compatible
- put maintainers after title
- remove unnecessary label in example
- Rework description to focus on what is implemented rather than what
may be implemented in the future.
