If the user is using an old Android image (version < 2) there are no special DTB pointers. What systems do in this case is to use the "second" area for a DTB, and this is what bootm is falling back to when booting and abootimg, see image-fdt.c function boot_get_fdt().
So since I need this on some PostmarkeOS systems to modify DTBs on-the-fly, make the abootimg also recognize and fall back to using "second" if the Android image header is < 2.
