[U-Boot] rockchip breakage with "spl: Remove overwrite of relocated malloc limit"

[Kever Yang <kever.yang@rock-chips.com>]

Hi Heiko,

That patch break all the Rockchip SoCs SPL which using spl_init().

Eddie send one patch for rk3288 by add a spl_early_init(), which is
under review, I also look forward for better solution.

Thanks,
