iommu/arm-smmu-v3: Enable HTTU for stage1 with io-pgtable mapping
If io-pgtable quirk flag indicates support for hardware update of
dirty state, enable HA/HD bits in the SMMUÂ CD and also set the DBM
bit in the page descriptor.
Now report the dirty page tracking capability of SMMUv3 and
select IOMMUFD_DRIVER for ARM_SMMU_V3 if IOMMUFD is enabled.
