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 SMMU 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.
