    ramips: Add support for the GnuBee Personal Cloud Two
    
    The GnuBee Personal Cloud Two crowdfunded on https://www.crowdsupply.com
    It is a low-cost, low-power, network-attached storage device.
    
    Specifications:
    
    - SoC: MediaTek MT7621AT
    - RAM: DDR3 512 MB
    - Flash: 32 MB
    - Six SATA ports for 3.5" Drives
    - One SDcard
    - One USB 3.0
    - Two USB 2.0
    - Gigabit Ethernet: Three Ports
    - UART 3.5mm Audio Jack or 3 pin header - 57600 8N1
    - Three GPIOs available on a pin header
    
    Flash instructions:
    
    The GnuBee Personal Cloud Two ships with libreCMC installed.
    libreCMC is a Free Software Foundation approved fork of LEDE/OpenWrt.
    As such one can upgrade using the webinterface or sysupgrade.
    
    Das U-Boot has multiple options for recovery or updates including :
    
    - USB
    - http
    - tftp
    
    Errata:
    - While there are three ethernet ports, the third requires support for
      the second GMAC. This will come in kernel 4.14.
    - The first hard drive slot has a clearance issue with the two fan
      headers. Workaround is to pull the headers out and connect the pins to
      jumper wires.
    - Using this device as a NAS is problematic with the 4.9 kernel as many
      /dev/sdX reads throw silent errors. The current theory behind this is
      some kind of unhandled DMA mapping error in the kernel. This is not an
      issue with kernel 4.4.
