iommu: disable smmu stalls on faulty transactions
Disable the SMMU stalls on faulty transactions by terminating it using
the CB.SCTLR register. Faulty transaction on a CB causes the back
pressure on the QSMMU transaction pipe which inturn affect the other
masters using the same SMMU. Pass the DOMAIN_ATTR_CB_STALL_DISABLE flag
to iommu_domain_set_attr api in order to use this feature.
