    ramips: add support for Ubiquiti EdgeRouter X-SFP
    
    This patch adds support for the Ubiquiti EdgeRouter X-SFP and
    improves support for the EdgeRouter X (PoE-passthrough).
    
    Specification:
    - SoC: MediaTek MT7621AT
    - Flash: 256 MiB
    - RAM: 265 MiB
    - Ethernet: 5 x LAN (1000 Mbps)
    - UART: 1 x UART on PCB (3.3V, RX, TX, GND) - 57600 8N1
    - EdgeRouter X:
      - 1 x PoE-Passtrough (Eth4)
      - powered by Wallwart or passive PoE
    - EdgeRouter X-SFP:
      - 5 x PoE-Out (24V, passive)
      - 1 x SFP (unknown status)
      - powered by Wallwart (24V)
    
    Doesn't work:
    * SoC has crypto engine but no open driver.
    * SoC has nat acceleration, but no open driver.
    * This router has 2MB spi flash soldered in but MT
      nand/spi drivers do not support pin sharing,
      so it is not accessable and disabled. Stock
      firmware could read it and it was empty.
    
    Installation
    
    via vendor firmware:
    - build an Initrd-image (> 3MiB) and upload the factory-image
    - initrd can have luci-mod-failsafe
    - flash final firmware via LuCI / sysupgrade on rebooted system
    
    via TFTP:
    - stop uboot into tftp-load into option "1"
    - upload factory.bin image
