The commit ("iommu/mediatek: Enlarge the validate PA range
for 4GB mode") introduce the following build error:
drivers/iommu/mtk_iommu.c: In function 'mtk_iommu_hw_init':
>> drivers/iommu/mtk_iommu.c:536:30: error: 'const struct mtk_iommu_data'
has no member named 'm4u_type'; did you mean 'm4u_dom'?
if (data->enable_4GB && data->m4u_type != M4U_MT8173) {
This patch fix it, use "m4u_plat" instead of "m4u_type".

1) In the v2 of mt2712 iommu support patch-set, We changed a variant
name from "m4u_type" to "m4u_plat", But I'm sorry that I forgot to
change it in the later patch.
2) This patch is based on [1].

3) I cann't find the commit id of the patch ("iommu/mediatek: Enlarge
the validate PA range for 4GB mode") in the [2].
So I don't write the commit id for that patch in the commit message.
