Subject: ARM: dts: stm32: Add support for the emtrion emSBC-Argon

This patch presents the DT patches for the emtrion GmbH
Argon board series. They are available with STM32MP157
from STMicroelectronics with 512 MByte Memory.

The devicetree stm32mp157c-emstamp-argon.dtsi is the common part
providing the module components and the basic support for the SoC.
The support for the emSBC-Argon baseboard in the developer-kit
configuration is provided by the stm32mp157c-emsbc-argon.dts file.
