On rockchip platforms, SPI boot image creation is not
straightforward like MMC boot image creation where former
requires to specify tpl, spl in multimage format in mkimage,
and later simply do a concatenate mkimaged-tpl with spl.

On this note, let drop rkspi image type creation via kbuild
and let inform via rockchip.rst
