At present, All root bus will go through iommu when iommu is configured, which is not flexible. So this add option to enable/disable iommu for primary bus and pxb root bus. When iommu is enabled for the root bus, devices attached to it will go through iommu. When iommu is disabled for the root bus, devices will not go through iommu accordingly.
