    realtek: make DGS-1210 u-boot-env partition writeable
    
    We are close to provide enduser friendly OpenWrt images for DGS-1210
    switches that do not need serial console. Nevertheless a small bit is
    missing. We cannot switch back to the vendor partition or initiate a
    download of a vendor firmware image. To issue this from inside OpenWrt
    we need write access to U-Boot environment.
    
    Case 1: Switch back to secondary (vendor) image
    > fw_setenv bootcmd run addargs\; bootm 0xb4e80000
    > fw_setenv image /dev/mtdblock7
    > reboot
    
    Case 2: Issue D-Link Network Assistant based download on next reboot.
    This is a combination of some vendor specific protocol (DDP) and a
    TFTP download afterwards.
    > fw_setenv bootstop on
    > reboot
    
    Allow these commands by opening up u-boot-env for write access.
    Tested on DGS-1210-20.
