iommu/mediatek: Add mtk_iommu_bank_data structure

Browse source

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.
