    This commit enables Kconfig.
    Going forward, we use Kconfig for the board configuration.
    mkconfig will never be used. Nor will include/config.mk be generated.
    
    Kconfig must be adjusted for U-Boot because our situation is
    a little more complicated than Linux Kernel.
    We have to generate multiple boot images (Normal, SPL, TPL)
    from one source tree.
    Each image needs its own configuration input.
    
    Usage:
    
    Run "make <board>_defconfig" to do the board configuration.
    
    It will create the .config file and additionally spl/.config, tpl/.config
    if SPL, TPL is enabled, respectively.
    
    You can use "make config", "make menuconfig" etc. to create
    a new .config or modify the existing one.
    
    Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
    and do likewise for tpl/.config file.
    
    The generic syntax of configuration targets for SPL, TPL is:
    
      <target_image>/<config_command>
    
    Here, <target_image> is either 'spl' or 'tpl'
          <config_command> is 'config', 'menuconfig', 'xconfig', etc.
