This seems like a pretty niche scenario, maybe we should just keep a global for the max ASID?
Otherwise we need a code to change the ASID, even for non-SVA domains, when the domain is installed in different devices if the current ASID is over the instance max..
Ideally domain ASID would be selected at domain allocation time.
