[RFC v2 4/8] iommu: Add a list of iommu_reserved_region in iommu_domain

Introduce a new iommu_reserved_region struct. This embodies an IOVA reserved region that cannot be used along with the IOMMU API. The list is protected by a dedicated mutex. An iommu domain now owns a list of those. Signed-off-by: Eric Auger --- ---
