    ath79: add support for gl-e750
    
    The gl-e750 is a portable travel router that gives you safe access to
    the internet while traveling.
    
    Specifications:
    - SoC: Qualcomm Atheros AR9531 (650MHz)
    - RAM: 128 MB DDR2
    - Flash: 16 MB SPI NOR (W25Q128FVSG) + 128 MB SPI NAND (GD5F1GQ4UFYIG)
    - Ethernet: 10/100: 1xLAN
    - Wireless: QCA9531 2.4GHz (bgn) + QCA9887 5GHz (ac)
    - USB: 1x USB 2.0 port
    - Switch: 1x switch
    - Button: 1x reset button
    - OLED Screen: 128*64 px
    
    MAC addresses based on vendor firmware:
    LAN *:a0 art 0x0
    2.4GHz *:a1 art 0x1002
    5GHz *:a2 art calculated from art 0x0 + 2
    
    Flash firmware:
    Since openwrt's kernel already exceeds 2MB, upgrading from the official
    version of GL-inet (v3.100) using the sysupgrade command will break the
    kernel image. Users who are using version 3.100 can only upgrade via
    uboot. The official guidance for GL-inet is as follows:
    https://docs.gl-inet.com/en/3/troubleshooting/debrick/
    
    In the future, GL-inet will modify the firmware to support the sysupgrade
    command, so users will be able to upgrade directly with the sysupgrade
    command in future releases.
    
    OLED screen control:
    OLED controller is connected to QCA9531 through serial port, and can send
    instructions to OLED controller directly through serial port.
    Refer to the links below for a list of supported instructions:
