AMD IOMMU alias handling cleanups and code removal

Hi,

This patch-set cleans up the alias handling code in the AMD IOMMU driver. Most of the alias handling is done already in the IOMMU group code. Only the handling of request-ids that are not backed by a 'struct pci_dev' still needs to happen in the AMD IOMMU driver, as the IOMMU group code has no way of handling that.

A few other cleanups which accumulated during implemented this are also included in this patch-set.

Regards,

Joerg
