Jan Luebbe 7ae350a030 arm: mxs: olinuxino: move DRAM config tuning to SPL
The weak mxs_adjust_memory_params function is called from spl_mem_init.c,
so it must be linked into the SPL to have an effect. Move it from
mx23_olinuxino.c to spl_boot.c.

This change was verified by reading back the register values.
