image: fix Android ramdisk support when dtb is specified

If a dtb is specified on the command-line, the Android boot image ramdisk
will not be found. Fix this so that we can specify the ramdisk address and
dtb address. The syntax is to enter the Android boot image address for
both the kernel and ramdisk.
