arm64: dts: freescale: Add the GOcontroll Moduline Display baseboard 



The Moduline Display platform is a part of the wider GOcontroll Moduline
ecosystem. These are embedded controllers that focus on modularity with
their swappable IO modules.

The base Moduline Display board includes a board-to-board connector with
various busses to enable adding new display types required by the
application. It includes 2 Moduline IO module slots, a simple mono
codec/amplifier, a four channel adc, 2 CAN busses, an RTC and optional
wifi/bluetooth.

busses to the display adapter include:
- 4 lane LVDS
- 4 lane MIPI-DSI
- 4 lane MIPI-CSI
- HDMI 2.0a
- USB 2.0
- I2S
- I2C
- SPI

Also a couple of GPIO and PWM pins for controlling various ICs on the
display adapter board.
