Joerg Roedel 7139a2e929 iommu/amd: Ignore BUS_NOTIFY_UNBOUND_DRIVER event 
Detaching a device from its domain at this event is
problematic for several reasons:

	* The device might me in an alias group and
	  detaching it will also detach all other devices in
	  the group. This removes valid DMA mappings from
	  the other devices causing io-page-faults and lets
	  these devices fail.

	* Devices might have unity mappings specified by the
	  IVRS table. These mappings are required for the
	  device even when no device driver is attached.
	  Detaching the device from its domain in driver
	  unbind will also remove these unity mappings.

This patch removes the handling of the BUS_NOTIFY_UNBOUND_DRIVER
event to prevent these issues and align it better with the
behavior of the VT-d driver.
