Since Linux v3.17, the kernel's Image header includes a field image_size,
which gives the total size of the kernel including unpopulated data
sections such as the BSS). If this is present, then return it from
load_aarch64_image() as the true size of the kernel rather than
just using the size of the Image file itself. This allows the code
which calculates where to put the initrd to avoid putting it in
the kernel's BSS area.
This means that we should be able to reliably load kernel images
which are larger than 128MB without accidentally putting the
initrd or dtb in locations that clash with the kernel itself.
