iommu/core: Convert iommu_found to iommu_present
With per-bus iommu_ops the iommu_found function needs to work on a bus_type too. This patch adds a bus_type parameter to that function and converts all call-places. The function is also renamed to iommu_present because the function now checks if an iommu is present for a given bus and does not check for a global iommu anymore. Signed-off-by: Joerg Roedel <>
