x86/amd-iommu: Use dev->arch->iommu to store iommu related information
This patch changes IOMMU code to use dev->archdata->iommu to store information about the alias device and the domain the device is attached to. This allows the driver to get rid of the amd_iommu_pd_table in the future. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
