    ramips: add support for TP-Link RE650 v2
    
    TP-Link RE650 v2 is largely similar to v1 that
    is already supported by OpenWrt. Notable differences
    is differnt SPI Flash - 8 MB instead of 16 MB
    (from cFeon instead of Winbond) and a different
    configuration of PCIE connections to wifi chips.
    Otherwise it's largely the same product as v1
    
    Hardware specification:
    
    - SoC 880 MHz - MediaTek MT7621AT
    - 128 MB of DDR3 RAM
    - 8 MB - cFeon QH64A-104HIP
    - 4T4R 2.4 GHz - MediaTek MT7615E
    - 4T4R 5 GHz - MediaTek MT7615E
    - 1x 1 Gbps Ethernet - MT7621AT integrated
    - 7x LEDs (Power, 2G, 5G, WPS(x2), Lan(x2))
    - 4x buttons (Reset, Power, WPS, LED)
    - UART pinout - GND, RX, TX, labeled in the middle of the PCB,
      requires soldering because they're not through holes.
    
      Serial console @ 57600,8n1
    
    Flash instructions:
    
    Upload
    openwrt-ramips-mt7621-tplink_re650-v2-squashfs-factory.bin
    from the RE650 web interface.
    
    TFTP recovery to stock firmware:
    I didn't try recovering back to the stock firmware, however,
    if there is such process for other RExxx devices, it seems like
    it could be similar here.
