    kernel: fitimage: support device tree compiler options
    
    This introduces a new variable to set the device tree compiler options while
    calling mkimage ('-D' option). By default, this variable is not set but it can
    be defined in a configuration file, as following example:
    
    UBOOT_MKIMAGE_DTCOPTS = "-I dts -O dtb -p 2000"
    
    (From OE-Core rev: 9a3f541da305c75418c2eec75ade902717a01b69)
