MicroGEA STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.

General features:
- STM32MP157AAC
- Up to 1GB DDR3L-800
- 512MB Nand flash
- I2S

MicroGEA STM32MP1 needs to mount on top of Engicam MicroDev carrier
boards for creating complete platform solutions.

Add support for it.

If STM32MP157AAC is soldered onto this board, you should include SoC 
dtsi here and no into MicroDev 2.0 board. No ?

+#include "stm32mp15-pinctrl.dtsi"

No, it's an SoM dtsi. and it can be associated with the respective
carrier board and include files are attached in its dts.

Please check the next patches on this series.
