arm64: dts: imx8mm: Add Engicam i.Core MX8M Mini C.TOUCH 2.0

Engicam C.TOUCH 2.0 is an EDIMM compliant general purpose Carrier
board.

Genaral features:
- Ethernet 10/100
- Wifi/BT
- USB Type A/OTG
- Audio Out
- CAN
- LVDS panel connector

i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini from Engicam.

i.Core MX8M Mini needs to mount on top of this Carrier board for
creating complete i.Core MX8M Mini C.TOUCH 2.0 board.

Add support for it.
