dt-bindings: watchdog: Add missing clocks requirement in Samsung SoC watchdog
The Samsung SoC watchdog driver always required providing a clock (either through platform data or from DT). However when bindings were added in commit 9487a9cc7140 ("watchdog: s3c2410: Add support for device tree based probe"), they missed the requirement of clock.
