[PATCH v3 05/13] ARM: dts: stm32: add iwdg1 node on stm32mp151 SoC

[Antonio Borneo <antonio.borneo@foss.st.com>]

From: Amelie Delaunay <amelie.delaunay@foss.st.com>

On STM32MP15x boards where IWDG1 is exposed as a non-secure
watchdog, Linux must register and periodically ping it if it was
started by an earlier boot stage.

Add the IWDG1 node to the STM32MP151 SoC device tree as a child
of the ETZPC node.
