Since commit 44c6e6591cb451ae606f8bde71dd5fb7b4002544
"rename _end to __bss_end__" , the _end was removed.
But we need it now for separated device tree control,
ie, CONFIG_OF_SEPARATE .
Though _end used to be the end of u-boot.bin image,
we mark it up and relocate the dtb part of u-boot-dtb.bin
here to be used by fdtdec_setup().
