    mvebu: fix sysupgrade
    
    mvebu was modifying RAMFS_COPY_BIN and RAMFS_COPY_DATA from a
    sysupgrade_pre_upgrade hook. As the ramfs is created from stage2, this
    did not have an effect anymore after the staged sysupgrade changes.
    
    As it doesn't really hurt to copy fw_printenv and fw_setenv
    unconditionally, simply add them in /lib/upgrade/platform.sh, so stage2
    will see them.
    
    Config copying is moved to a function called by platform_copy_config, where
    it belongs.

    Fixes: FS#821
    Fixes: 30f61a34b4cf "base-files: always use staged sysupgrade"
