Add support for the IOMMU on MT8167
Signed-off-by: Fabien Parent <fpar...@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.
