This commit breaks booting non-fdt Android images (the kernel doesn't
find the initramfs, and neither does U-Boot).

The test to enter the code block where Android ramdisk support was moved
is accessed with:
else if (select || genimg_has_config(images)) {

However, in a non-fdt context, select is NULL and genimg_has_config
returns 0.

I suggest we either duplicate Android ramdisk support in the non-fdt
path or adapt the condition to enter the code block where it was moved.
