rockchip: Print a message when returning to the bootrom At present if the return to bootrom fails (e.g. because you are not using the Rockchip's bootrom's pointer table in MMC) then the board prints SPL message and hangs. Print a message first if we can, to help in understanding what happened when it hangs.

rockchip: use puts instead of printf when back to bootrom printf will increase the code size more than 1kb, but platform like rk3036 has no enough space for it.
