Samuel Holland 44de13d945 sunxi: Support SPL in both eGON and TOC0 images
SPL uses the image header to detect the boot device and to find the
offset of the next U-Boot stage. Since this information is stored
differently in the eGON and TOC0 image headers, add code to find the
correct value based on the image type currently in use.
