IOMMU Updates for Linux v4.5

The updates include:

	* Small code cleanups in the AMD IOMMUv2 driver

	* Scalability improvements for the DMA-API implementation of the
	  AMD IOMMU driver. This is just a starting point, but already
	  showed some good improvements in my tests.

	* Removal of the unused Renesas IPMMU/IPMMUI driver

	* Updates for ARM-SMMU include:

		* Some fixes to get the driver working nicely on
		  Broadcom hardware

		* A change to the io-pgtable API to indicate the unit in
		  which to flush (all callers converted, with Ack from
		  Laurent)

		* Use of devm_* for allocating/freeing the SMMUv3
		  buffers

	* Some other small fixes and improvements for other drivers
