    ramips: add support for minew g1-c
    
    The minew g1-c is a smart home gateway / BLE gateway.
    A Nordic nRF52832 is available via USB UART (cp210x) to support BLE.
    The LED ring is a ring of 24x ws2812b connect to a generic GPIO (unsupported).
    There is a small LED which is only visible when the device is open which
    will be used as LED until the ws2812b is supported.
    The board has also a micro sdcard/tfcard slot (untested).
    The Nordic nRF52832 exposes SWD over a 5pin header (GND, VCC, SWD, SWC, RST).
    The vendor uses an older OpenWrt version, sysupgrade can be used via
    serial or ssh.
    
    CPU:            MT7628AN / 580MHz
    RAM:            DDR2 128 MiB RAM
    Flash:          SPI NOR 16 MiB W25Q128
    Ethernet:       1x 100 mbit (Port 0) (PoE in)
    USB:            USB hub, 2x external, 1x internal to USB UART
    Power:          via micro usb or PoE 802.11af
    UART:           3.3V, 115200 8n1
