IOMMU-Fixes for Linux v4.9-rc4

Two places need fixing:

	* Four patches from Robin Murphy fix several issues with the
	  recently merged generic DT-bindings support for arm-smmu
	  drivers

	* A fix for a dead-lock issue in the VT-d driver, which shows up
	  on iommu hotplug
iommu/vt-d: Fix dead-locks in disable_dmar_iommu() path

It turns out that the disable_dmar_iommu() code-path tried
to get the device_domain_lock recursivly, which will
dead-lock when this code runs on dmar removal. Fix both
code-paths that could lead to the dead-lock.
