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

Genaral features:
- Ethernet 10/100
- USB Type A
- Audio Out
- microSD
- LVDS panel connector
- Wifi/BT (option)
- UMTS LTE with sim connector (option)

MicroGEA STM32MP1 is a STM32MP157A based Micro SoM.

MicroGEA STM32MP1 needs to mount on top of this MicroDev 2.0 board
for creating complete MicroGEA STM32MP1 MicroDev 2.0 Carrier board.

Add support for it.
