Move addresses for kernel, ramdisk and fdt blob to own variables. Add dtb blob loading to all existing boot scripts, dtb filenames were taken from vanilla kernel. Introduce new boot script bootcmd_legacy, which only loads a kernel and a ramdisk. Make this the default boot script. This should also restore the behaviour of the original bootloader.
