[libvirt PATCH v2 3/7] qemu: add IOMMU model amd

From: Ján Tomko <jtomko(a)redhat.com&gt; Introduce a new IOMMU device model 'amd', both the parser and the formatter for QEMU because of our enum warnings. https://issues.redhat.com/browse/RHEL-50560 Signed-off-by: Ján Tomko <jtomko(a)redhat.com&gt;
