cd90a518b0 vfio/pci: Register handler for iommu fault 
We use the new extended IRQ VFIO_IRQ_TYPE_NESTED type and
VFIO_IRQ_SUBTYPE_DMA_FAULT subtype to set/unset
a notifier for physical DMA faults. The associated eventfd is
triggered, in nested mode, whenever a fault is detected at IOMMU
physical level.

The actual handler will be implemented in subsequent patches.
