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
