If smi.h include this file, it also is ok. then these two
files(mtk_iommu.h and mtk_smi.c) don't need include this.

the MTK_LARB_NR_MAX only is used in mtk_iommu.h and mtk_smi.c directly,
thus I use that two files include this file currently. locally I think
it may be helpful for readable.

is this ok?
