iommu: Introduce direct mapped region handling
Add two new functions to the IOMMU-API to allow the IOMMU drivers to export the requirements for direct mapped regions per device. This is useful for exporting the information in Intel VT-d's RMRR entries or AMD-Vi's unity mappings. Signed-off-by: Joerg Roedel <jroedel@suse.de>
