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.

Changes since v1:
1. Indent example with four spaces (more readable),
2. Add also missing required entries for clocks.
