iommu/exynos: Implement fault handling on SysMMU v7
SysMMU v7 has a bit different registers for getting the fault info:
- there is one single register (MMU_FAULT_VA) to get the fault address
- fault access type (R/W) can be read from MMU_FAULT_TRANS_INFO
register now
- interrupt status register has different bits w.r.t. previous SysMMU
versions
- VM and non-VM layouts have different register addresses
Add correct fault handling implementation for SysMMU v7, according to
all mentioned differences. Only VID #0 (default) is handled, as VM
domains support is not implemented yet.
