    ramips: Add support for Dual-Q H721
    
    Dual-Q H721 is a router platform board, it is the smaller model of
    the U7621-06.
    
    The device has the following specifications:
    
    MT7621AT (880 MHz)
    256 of RAM (DDR3)
    16 MB of FLASH (MX25l12805d SPI)
    5x 1 Gbps Ethernet (MT7621 built-in switch)
    1x M.2 (NGFF) 3.7V 3A max for 5G M.2 Modem work at USB3.0 mode
    1x Minipcie 3.7V 3A max for LTE Modem work at USB2.0 Mode
    2x Minipcie for WIFI card
    4x Lan+1x Wan 10/100M/1000M RJ45 port
    14x LEDs (1x GPIO-controlled)
    1x reset button
    1x UART header (4-pins)
    1x mico SD-card reader
    1x DC jack for main power (5~27 V)
    
    The following has been tested and is working:
    
    Ethernet switch
    miniPCIe slots (tested with Wi-Fi cards and LTE modem cards)
    miniSIM slot (works with normal size simcard)
    sysupgrade
    reset button
    micro SD-card reader
    
    Installation:
    
    This board has no locked down bootloader. The seller can be asked to
    install openwrt, so upgrades are standard sysupgrade method.
    
    Recovery:
    
    This board contains a Chinese, closed-source bootloader called Breed
    (Boot and Recovery Environment for Embedded Devices). Breed supports web
    recovery and to enter it, you keep the reset button pressed for around
    5 seconds during boot. Your machine will be assigned an IP through DHCP
    and the router will use IP address 192.168.1.1. The recovery website is
    in Chinese, but is easy to use. Click on the second item in the list to
    access the recovery page, then the second item on the next page is where
    you select the firmware. In order to start the recovery, you click the
    button at the bottom.

    [change author name (used SoB one), add ethernet pinctrl,
     apply sorting to device recipe]
