    ramips: improve compatibility for Youku YK-L2 and YK-L1 series
    
    Add UIMAGE_NAME and UIMAGE_MAGIC to allow users to directly install
    initramfs-kernel.bin from the stock firmware Web UI. At the same time,
    this change makes it possible to boot OpenWrt with the official u-boot.
    
    Notice:
    Since the stock firmware is based on OpenWrt and the configuration
    will be retained by default during the upgrade process, so we must use
    initramfs-kernel.bin to do a initial installation. After the system
    restarts, install sysupgrade.bin and do not retain any configuration.
