I should be able to split these changes into an independent series on top
of upstream. I did not include a base-commit because the series is
currently based on other CCA patches, solely to enable testing of the
complete stack.

The full tree, including the other CCA changes, is available at:

https://git.gitlab.arm.com/linux-arm/linux-cca/-/tree/cca/scratch/vdevice-tdi?ref_type=heads

For the next iteration, I will rebase the IOMMUFD series onto the upstream
kernel and include the base-commit trailer.
