iommu/vt-d: Use BUS_NOTIFY_REMOVED_DEVICE in hotplug path (2016-02-29 23:55:16 +0100)

----------------------------------------------------------------
IOMMU Fixes for Linux v4.5-rc6

Including one fix for Intel VT-d:

* Use BUS_NOTIFY_REMOVED_DEVICE notifier to unbind a device from its domain _after_ it has been unbound from its driver. This fixes a BUG_ON being triggered in the PCI hotplug path.

And three for AMD IOMMU:

* Add a workaround for a hardware issue with ATS in use

* Fix ATS enable/disable balance when a device is removed

* Fix a boot warning being triggered when the system has IOMMU performance counters and PCI device 00:00.0 is not covered by the IOMMU
