hw/arm/smmu-common: Allow domain invalidation for NH_ALL/NSNH_ALL

Browse Source 
NH_ALL/NSNH_ALL corresponds to a domain granularity invalidation,
ie. all the notifier range gets invalidation, whatever the ASID.
So let's set the granularity to IOMMU_INV_GRAN_DOMAIN to allow
the consumer to benefit from the info if it can.
