[U-Boot] [PATCH v2 1/3] image: Make image_get_fdt work like image_get_{ram_disk, kernel}

[Stephen Warren]

image_get_ram_disk() and image_get_kernel() perform operations in a
consistent order. Modify image_get_fdt() to do things the same way.
This allows a later change to insert some image header manipulations
into these three functions in a consistent fashion.

v2: New patch
