    ramips: add support for Ravpower WD03
    
    The RavPower WD03 is a battery powered SD card reader and a USB port.
    
    Specifications:
    SOC:     MediaTek MT7620N
    BATTERY: 6000mah
    WLAN:    802.11bgn
    LAN:     1x 10/100 Mbps Ethernet
    USB:     1x USB 2.0 (Type-A)
    RAM:     PM Tech PMD708416CTR-5CN 32 MB
    FLASH:   Holtek HT66F40 - 8 MB Flash
    LED:     Power button and 4 leds to indicate power level of the
             battery (could not get control of that)
    INPUT:   Power, reset button
    OTHER:   USB SD-Card reader with card detect on GPIO#42
    
    Tested and working:
     - Ethernet
     - 2.4 GHz WiFi (Correct MAC-address)
     - installation from tftp
     - OpenWRT sysupgrade (Preserving and non-preserving)
     - LEDs
     - Buttons
    
    Installation:
     - Download the sysupgrade image
     - Place it in the root of a clean TFTP server running on your computer.
     - Rename the image to "kernel" — be sure there is no file extension.
     - Plug the WD03 into your computer via ethernet.
     - Set your computer to use 10.10.10.254 as its IP address.
     - With your WD03 shut down, hold down the power button until the first
       white LED lights up.
     - Push and hold the reset button and release the power button. Continue
       holding the reset button for 30 seconds or until it begins searching
       for files on your TFTP server, whichever comes first.
     - The WD03 (10.10.10.128) will look for your computer at 10.10.10.254
       and install the kernel file. Once it has finished installation of the
       kernel file, it will search for a (nonexistent) rootfs file — when it
       begins searching for this file, shut down the WD03 by holding the
       power button normally.
     - Start up your WD03 normally.
