Rockchip SoCs allow the spl code to be rc4-encoded, not only the image header, but only newer SoCs allow this encoding to be disabled. The rk3188 is not part of those and requires its boot code to be rc4-encoded with the regular key. So add the ability to do this encoding via a setting on a per-soc basis when building spl images.
