IOMMU: Make iommu_ops per-bus_type

Hi,

here is the third version of the patch-set to make the iommu_ops used in
the iommu-api a bus_type property. This will allow us to move code out
of the iommu drivers into generic code and it simplifies the
implementation of the Alex' device-group property.

It converts all iommu drivers to use the new registration interface and
completly removes the register_iommu interface.

Please let me know of any remaining objections. If there are no I would
be very happy about Acked-By's :)

Regards,

	Joerg

Changes v2->v3:
	* Moved bus_set_iommu() to drivers/iommu/iommu.c to get rid of
	  the CONFIG_IOMMU_API #ifdef around it in bus.c

Changes v1->v2:

        * Added kernel-doc comments to bus_set_iommu function
        * Removed iommu.h include from device.h and added a forward
          declaration for struct iommu_ops
