Ruslan Bukin 59e37c8a54 Start splitting-out the Intel DMAR busdma backend to a generic place, ... so it can be used on other IOMMU systems. Provide MI iommu_unit, iommu_domain and iommu_ctx structs in sys/iommu.h; use them as a first member of MD dmar_unit, dmar_domain and dmar_ctx. Change the namespace in DMAR backend: use iommu_ prefix instead of dmar_. Move some macroses and function prototypes to sys/iommu.h.
