    mediatek: add support for Airpi AP3000M
    
    This adds support for the Airpi AP3000M 5G CPE based on MediaTek MT7981B.
    
    Specifications:
    
    SoC: MediaTek MT7981B (dual-core ARM Cortex-A53)
    RAM: 1GB DDR4
    Storage: 8GB or 16GB eMMC
    Ethernet: 1x 2.5GbE LAN, 1x 1GbE WAN
    Wireless: 2.4GHz/5GHz 802.11ax
    Buttons: Reset, WPS
    LEDs: System, 2.4GHz WiFi, 5GHz WiFi
    Cooling: PWM-controlled fan
    Expansion: M.2 slot for 5G modem
    
    The factory partition (mmcblk0p2) is empty in stock firmware.
    Execute via SSH before flashing OpenWrt:
    ```
    dd if=/lib/firmware/MT7981_iPAiLNA_EEPROM.bin of=/dev/mmcblk0p2 bs=4k count=1
    MAC addresses
    ```
    Fixed MAC addresses are derived by macaddr_generate_from_mmc_cid.
    
    Installation via U-Boot web page
    
    Set static IP 192.168.88.2/255.255.255.0 on your computer.
    Connect to the 1GbE port (WAN) and hold the reset button while booting the device. Wait for about 6 seconds, and release the reset button.
    Open U-boot web page on your browser at http://192.168.88.1
    Select the OpenWRT sysupgrade image, upload it, and start the upgrade.
    Wait for automatic reboot.
    Installation via sysupgrade
    
    Flash the sysupgrade file via LuCI upgrade page without saving the settings.
