Subject: [PATCH RESEND v2 4/6] dt-bindings: watchdog: sun4i: Add the watchdog clock

From: Maxime Ripard <maxime.ripard@...tlin.com>

The Allwinner watchdog has a clock that has been described in some DT, but
not all of them.

The binding is also completely missing that description. Let's add that
property to be consistent.
