iommu/arm-smmu-v3: Add support for Hardware Translation Table Update

hulk inclusion
category: feature
bugzilla: 14369
CVE: NA
-------------------

If the SMMU supports it and the kernel was built with HTTU support, enable
hardware update of access and dirty flags. This is essential for shared
page tables, to reduce the number of access faults on the fault queue.

We can enable HTTU even if CPUs don't support it, because the kernel
always checks for HW dirty bit and updates the PTE flags atomically.
