    ath79: add support for GL.iNet GL-MiFi
    
    Add support for the ar71xx supported GL.iNet GL-MiFi to ath79.
    
    Specifications:
     - Atheros AR9331
     - 64 MB of RAM
     - 16 MB of FLASH (SPI NOR)
     - 2x 10/100/1000 Mbps Ethernet
     - 2.4GHz (AR9330), 802.11b/g/n
     - 1x USB 2.0 (vbus driven by GPIO)
     - 4x LED, driven by GPIO
     - 1x button (reset)
     - 1x mini pci-e slot (vcc driven by GPIO)
    
    Flash instructions:
    
    Vendor software is based on openwrt so you can flash the sysupgrade
    image via the vendor GUI or using command line sysupgrade utility.
    Make sure to not save configuration over reflash as uci settings
    differ between versions.
    
    Note on MAC addresses:
    
    Even though the platform is capable to providing separate MAC addresses
    to the interfaces vendor firmware does not seem to take advantage of
    that. It appears that there is only single unique pre-programmed
    address in the art partition and vendor firmware uses that for
    every interface (eth0/eth1/wlan0). Similar behaviour has also been
    implemented in this patch.
    
    Note on GPIOs:
    
    In vendor firmware the gpio controlling mini pci-e slot is named
    3gcontrol while it actually controls power supply to the entire mini
    pci-e slot. Therefore a more descriptive name (minipcie) was chosen.
    Also during development of this patch it became apparent that the
    polarity of the signal is actually active low rather than active high
    that can be found in vendor firmware.
    
    Acknowledgements:
    
    This patch is based on earlier work[1] done by Kyson Lok. Since the
    initial mailing-list submission the patch has been modified to comply
    with current openwrt naming schemes and dts conventions.
