Add support for the IOMMU on MT8167

Signed-off-by: Fabien Parent <fparent@baylibre.com>

V4;
	* Removed HAS_4GB_MODE flag since this SoC does not seem to support it
V3:
	* use LEGACY_IVRP_PADDR flag instead of using a platform data member
V2:
	* removed if based on m4u_plat, and using instead the new
	  has_legacy_ivrp_paddr member that was introduced in patch 2.
