    sunxi: add support for FriendlyArm Zeropi
    
    Specification
    
        CPU: Allwinner H3, Quad-core Cortex-A7 Up to 1.2GHz
        DDR3 RAM: 256MB/512MB
        Connectivity: 10/100/1000Mbps Ethernet
        USB Host: Type-A x 1
        MicroSD Slot x 1
        MicroUSB: for power input only
        Debug Serial Port: 4Pin, 2.54 mm pitch pin header
        Power Supply: DC 5V/2A
        PCB Dimension: 40 x 40 x 1.2mm
    
    Installation:
    
        Burn the image file to an SD Card with dd or any image burning tool
        Boot ZeroPi from the SD Card
    
    The following features are working and tested:
    
        Ethernet port 10/100/1000M Ethernet
    
    Remarks: SBC is mostly compatible and boots with FriendlyARM NanoPI M1 plus DTS also (zeropi has no working hdmi)
