iommu/mediatek: Separate mtk_iommu_data for v1 and v2

Prepare for adding the structure "mtk_iommu_bank_data". No functional
change. The mtk_iommu_domain in v1 and v2 are different, we could not add
current data as bank[0] in v1 simplistically.

Currently we have no plan to add new SoC for v1, in order to avoid affect
v1 when we add many new features for v2, I totally separate v1 and v2 in
this patch, there are many structures only for v2.
