Subject: [PATCH v5 28/34] iommu/mediatek: Add mtk_iommu_bank_data structure
Prepare for supporting multi-banks for the IOMMU HW, No functional change.
Add a new structure(mtk_iommu_bank_data) for each a bank. Each a bank have
the independent HW base/IRQ/tlb-range ops, and each a bank has its special
iommu-domain(independent pgtable), thus, also move the domain information
into it.
In previous SoC, we have only one bank which could be treated as bank0(
bankid always is 0 for the previous SoC).
After adding this structure, the tlb operations and irq could use
bank_data as parameter.
