iommu/mediatek: Initialise bank HW for each a bank
The mt8195 IOMMU HW max support 5 banks, and regarding the banks' registers, it looks like: ---------------------------------------- |bank0 | bank1 | bank2 | bank3 | bank4| ---------------------------------------- |global | |control| null |regs | ----------------------------------------- |bank |bank |bank |bank |bank | |regs |regs |regs |regs |regs | | | | | | | ----------------------------------------- Each bank has some special bank registers and it share bank0's global control registers. this patch initialise the bank hw with the bankid. In the hw_init, we always initialise bank0's control register since we don't know if the bank0 is initialised. Additionally, About each bank's register base, always delta 0x1000. like bank[x + 1] = bank[x] + 0x1000.
