We only formatted the <sev> element when QEMU supported the feature when
in fact we should always format the element to make clear that libvirt
knows about the feature and the fact whether it is or isn't supported
depends on QEMU version, in other words if QEMU doesn't support the
feature we're going to format the following into the domain capabilities
XML:
<sev supported='no'/>
This patch also adjusts the RNG schema accordingly in order to reflect
the proposed change.

Add a path for UEFI VMs for AArch32 VMs, based on the path Debian is using.
libvirt is the de facto canonical location for defining where distros
should place these firmware images, so let's define this path here to try
and minimize distro fragmentation.
QEMU 2.8.0 adds support for unavailable-features in
query-cpu-definitions reply. The unavailable-features array lists CPU
features which prevent a corresponding CPU model from being usable on
current host. It can only be used when all the unavailable features are
disabled. Empty array means the CPU model can be used without
modifications.
We can use unavailable-features for providing CPU model usability info
in domain capabilities XML:
<domainCapabilities>
...
<cpu>
<mode name='host-passthrough' supported='yes'/>
<mode name='host-model' supported='yes'>
<model fallback='allow'>Skylake-Client</model>
...
</mode>
<mode name='custom' supported='yes'>
<model usable='yes'>qemu64</model>
<model usable='yes'>qemu32</model>
<model usable='no'>phenom</model>
<model usable='yes'>pentium3</model>
<model usable='yes'>pentium2</model>
<model usable='yes'>pentium</model>
<model usable='yes'>n270</model>
<model usable='yes'>kvm64</model>
<model usable='yes'>kvm32</model>
