Add device-tree for the MT8365-EVK board. The MT8365 EVK board
has the following IOs:
* DPI <-> HDMI bridge and HDMI connector.
* 2 audio jack
* 1 USB Type-A Host port
* 2 UART to USB port
* 1 battery connector
* 1 eMMC
* 1 SD card
* 2 camera connectors
* 1 M.2 slot for connectivity
* 1 DSI connector + touchscreen connector
* RPI compatible header
* 1 Ethernet port
