    ath79: add support for ZTE MF282
    
    The ZTE MF282 is a LTE router used (exclusively?) by the network operator
    "3".
    
    Specifications
    ==============
    
    SoC: QCA9563 (775MHz)
    RAM: 128MiB
    Flash: 8MiB SPI-NOR + 128MiB SPI-NAND
    LAN: 1x GBit LAN
    LTE: ZTE MF270 (Cat4), detected as P685M
    WiFi: QCA9880ac + QCA9560bgn
    
    MAC addresses
    =============
    
    LAN: from config
    WiFi 1: from config
    WiFi 2: +1
    
    Installation
    ============
    
    TFTP installation using UART is preferred. Disassemble the device and
    connect serial. Put the initramfs image as openwrt.bin to your TFTP server
    and configure a static IP of 192.168.1.100. Load the initramfs image by
    typing:
    
      setenv serverip 192.168.1.100
      setenv ipaddr 192.168.1.1
      tftpboot 0x82000000 openwrt.bin
      bootm 0x82000000
    
    From this intiramfs boot you can take a backup of the currently installed
    partitions as no vendor firmware is available for download.
    
    Once booted, transfer the sysupgrade image and run sysupgrade.
    
    LTE Modem
    =========
    
    The LTE modem is probably the same as in the MF283+, all instructions
    apply.
    
    Configuring the connection using modemmanager works properly, the modem
    provides three serial ports and a QMI CDC ethernet interface.
