Fix do_bootm_linux() so that multi-file images with FDT blob boot.
Fix incorrect blob address calculation in do_bootm_linux() that prevents booting the kernel from a multi-file image (kernel + initrd + blob). Also, make minor updates to the U-Boot's output and to the coding style. Signed-off-by: Bartlomiej Sieka <tur@semihalf.com>
