The DDR_MEM tag contains at most 10 areas, so we should default to 10 if Rockchip TPL blob is used. Note that it is technically possible we need more if one of those 10 areas overlaps with reserved memory area, forcing us to split it in two. But a default doesn't need to handle all cases, only most.
