PATCH v2 5/10 ARM: dts: stm32: Add Engicam MicroGEA STM32MP1 MicroDev 2.0 7" OF

In reply to Jagan Teki

7" OF is a capacitive touch 7" Open Frame panel solutions with
- 7" AUO B101AW03 LVDS panel
- EDT, FT5526 Touch

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

MicroDev 2.0 is a general purpose miniature carrier board with CAN, LTE and LVDS panel interfaces.

MicroGEA STM32MP1 needs to mount on top of MicroDev 2.0 board with pluged 7" OF for creating complete MicroGEA STM32MP1 MicroDev 2.0 7" Open Frame Solution board.

Add support for it.
