[PATCH v2 3/3] ARM: dts: sunxi: add support for NetCube Systems OpenNMC (dobermann)

[Lukas Schmid]

NetCube Systems OpenNMC is an open replacement for APC SmartSlot Management
Cards. It is based on the Nagami System-on-Module. It breaks out the
following interfaces:

- 10/100 Mbps Ethernet
- USB Type-C OTG using a TUSB320 (usb0)
- USB Type-C Console Port using a CH340 (uart3)
- USB Type-A Host with internal CH334 USB-Hub (usb1)
- MicroSD Slot with Card-Detect (mmc0)
- WiFi/Bluetooth using the modules built-in ESP32
- SmartSlot serial interface (uart4)
- DS3232 RTC with CR1220 Battery Backup
- Extension connector providing SPI,I2C,USB,CAN,UART for future use.
