vfio: Replace the iommu notifier with a device list
Instead of bouncing the function call to the driver op through a blocking
notifier just have the iommu layer call it directly.
Register each device that is being attached to the iommu with the lower
driver which then threads them on a linked list and calls the appropriate
driver op at the right time.
Currently the only use is if dma_unmap() is defined.
Also, fully lock all the debugging tests on the pinning path that a
dma_unmap is registered.
