[PATCH 5.16 1024/1039] dt-bindings: watchdog: Require samsung,syscon-phandle for Exynos7

From: Greg Kroah-Hartman

commit 33950f9a36aca55c2b1e6062d9b29f3e97f91c40 upstream.

Exynos7 watchdog driver is clearly indicating that its dts node must
define syscon phandle property. That was probably forgotten, so add it.
