Subject: [PATCH] qemu: Add virtio related options to vsock
Add virtio related options iommu, ats and packed as driver element attributes
to vsock devices. Ex:
<vsock model='virtio'>
<cid auto='no' address='3'/>
<driver iommu='on'/>
</vsock>

(cherry picked from commit bd112c9e0f7523b90bf1362cf60deea7db05a32b)
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1941820
Note: since the virtio option packed is not yet available in the code
version it will also not be available with this backported patch.
Conflicts: docs/formatdomain.rst:
converted changes into docs/formatdomain.html.in
src/conf/domain_conf.c:
resolved conflicts by moving the code into the correct methods
src/conf/domain_validate.c:
does not exist downstream. moved code to src/conf/domain_conf.c
src/qemu/qemu_validate.c:
does not exist downstream. can be neglected
