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
bits. This is in preparation, to enable it on the context descriptors of
stage 1 format.
