The SPRD serial driver need to know which serial port would be used as
console in an early period during initialization, otherwise console
init would fail since we added this feature[1].

So this patch add console to command line via devicetree.

I guess no comments on this, so resending this and add soc@kernel.org,
hope Arnd or Olof can help to merge into arch_arm tree.

Thanks,
Chunyan
