ar71xx: Add eTactica EG-200 support

EG-200 is a DIN rail mountable device with one ethernet port, wifi,
an RS-485 port, and an internal USB attached uSD card reader.

Two leds, "modbus" and "etactica" are managed by userspace applications
in factory firmware.

Flash instruction:
    Original firmware is based on OpenWrt.
    Use sysupgrade image directly in vendor GUI.
