Change jump_to_image_no_args() to a weak symbol to allow override by
SoC specific code.  This is required by tegra because the SPL runs on
a different CPU from the image it is loading, so tegra specific
initialization is required to start the host CPU.  Pass in spl_image
as a parameter for the same reason.
