iommu/arm-smmu-v3: Allow setting a S1 domain to a PASID

Browse source

The SVA cleanup made the SSID logic entirely general so all we need to do
is call it with the correct cd table entry for a S1 domain.

This is slightly tricky because of the ASID and how the locking works, the
simple fix is to just update the ASID once we get the right locks.
