This patch series adds a vhost-user VIRTIO device for SCMI.
It's similar to other similar vhost-user VIRTIO devices.

I'm aware of the work in progress by Alex Bennée to simplify similar devices
and avoid excessive code duplication.  I think the SCMI device support
doesn't bring anything special and it can be rebased on the given work
if/once it is merged.

The device has been tested with a prototype rust-vmm based
vhost-user-scmi daemon emulating a sensor device and a Linux guest OS
(the production version of the vhost-user daemon is developed at
https://github.com/mz-pdm/vhost-device/tree/scmi).

v3:
 - Rebased on master after one of the patches had been merged.
v2:
 - A missing trailing space additionally added in the comment typo fix.
 - A note about testing added above.
