Subject: [PATCH] [C57][C57-72] Add watchdog node to kernel dts
The watchdog feature is activated by default from the SCFW.
The watchdog node was already configured in the file `imx8qxp.dtsi`
that is included in C57's device tree.
This commit only copies the watchdog node to the linux device tree to
configure the timeout easier.
