stable inclusion from stable-v5.10.94 commit 21513c4615575c0b1640ddeb2114242de4ddf58c bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
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.
