    ramips: add support for D-Link DIR-1935 A1
    
    Add support for D-Link DIR-1935 A1 based on similarities to DIR-882 A1,
    DIR-867 A1 and other DIR-8xx A1 models. Existing DIR-882 A1 openwrt
    "factory" firmware installs without modificaitons via the D-Link
    Recovery GUI and has no known incompatibilities with the DIR-1935 A1.
    
    Changes to be committed:
           new file:   target/linux/ramips/dts/mt7621_dlink_dir-1935-a1.dts
           modified:   target/linux/ramips/image/mt7621.mk
           modified:   target/linux/ramips/mt7621/base-files/etc/board.d/01_leds
    
    Specifications:
    * Board: Not known
    * SoC: MediaTek MT7621 Family
    * RAM: 128 MB (DDR3)
    * Flash: 16 MB (SPI NOR)
    * WiFi: MediaTek MT7615 Family (x2)
    * Switch: 1 WAN, 4 LAN (Gigabit)
    * Ports: 1 USB 3.0
    * Buttons: Reset, WiFi Toggle, WPS
    * LEDs: Power (green/orange), Internet (green/orange), WiFi 2.4G (green),
            WiFi 5G (green)
    
    Notes:
    * 160MHz 5GHz is available in LuCi but does not appear to work (i.e. no
      SSID is visible in wifi scanning apps on other devices) with either
      official DIR-882 A1 firmware or a test build for the DIR-1935 A1 based
      on the 22.03.2 branch. 80 MHz 5GHz works.
    
    Serial port:
    * Untested (potential user damage/error)
    * Expected to be identical to other DIR-8xx A1 models:
            * Parameters: 57600, 8N1
            * Location: J1 header (close to the Reset, WiFi and WPS buttons)
            * Pinout: 1 - VCC
                      2 - RXD
                      3 - TXD
                      4 - GND
    
    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
