[PATCH v2 04/12] iommu: Replace device fault handler with iommu_queue_iopf()

[Lu Baolu]

The individual iommu drivers report iommu faults by calling
iommu_report_device_fault(), where a pre-registered device fault handler
is called to route the fault to another fault handler installed on the
corresponding iommu domain.

The pre-registered device fault handler is static and won't be dynamic
as the fault handler is eventually per iommu domain. Replace calling
device fault handler with iommu_queue_iopf().
