iommu: Add domain attribute to make faults non-fatal
During development, any IOMMU faults most likely need to be debugged
immediately. Allowing the system to continue to run has a tendency to
mask the original problem, which makes debugging more difficult. Some
drivers might want to make all faults fatal by default, unless
explicitly requested otherwise by a client. Add a domain attribute for
this.
