    ramips: add support for D-Link DIR-2660 A2
    
    This patch adds support for D-Link DIR-2660 A2.
    Based on the commit: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=b5dd746cbb1aaf91f4b68e9f3eda97413550d904,
    
    Both devices look identical, except for the A1/A2 designation.
    You can safely install the A1 firmware for the A2 – I've been testing it for several months as a DUMB AP – without any problems.
    
    Specifications:
    * SoC: MediaTek MT7621AT
    * RAM: 256 MB (DDR3)
    * Flash: 128 MB (NAND)
    * WiFi: MediaTek MT7615N (x2)
    * Switch: 1 WAN, 4 LAN (Gigabit)
    * Ports: 1 USB 2.0, 1 USB 3.0
    * Buttons: Reset, WPS
    * LEDs: Power (white/orange), Internet (white/orange), WiFi 2.4G (white),
            WiFi 5G (white), USB 3.0 (white), USB 2.0 (white)
    
    Notes:
    * WiFi 2.4G and WiFi 5G LEDs are wired directly to the wireless chips
    
    Installation:
    * D-Link Recovery GUI: power down the router, press and hold the reset
      button, then re-plug it. Keep the reset button pressed until the power
      LED starts flashing orange, manually assign a static IP address under
      the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1
    
    * Some modern browsers may have problems flashing via the Recovery GUI,
      if that occurs consider uploading the firmware through cURL:
    
        curl -v -i -F "firmware=@file.bin" 192.168.0.1
