iommu/arm-smmu-v3: Add feature detection for HTTU
If the SMMU supports it and the kernel was built with HTTU support,
Probe support for Hardware Translation Table Update (HTTU) which is
essentially to enable hardware update of access and dirty flags.
Probe and set the smmu::features for Hardware Dirty and Hardware Access

stage 1 format.
