The clock for this driver switched to the common clock controller driver.
Therefore, update common clock properties for watchdog in the binding document.
And this matched this example with the actual dts.

wdt: isn't needed in the example, and I question if it
really improves the quality of the example to remove
timeout-sec.

Guenter

Hi Guenter,

Thanks for your review.

OK, I make a fix that doesn't remove timeout-sec.
