I was confused previously by the fact that the DTB is required,
despite gem5 autogenerating a default one if it is not provided.
TODO: why is the generated one not correct?

Move arm to virt armv7, unify arm QEMU and gem5 builds
...
gem5 requires armv7, and we learnt that the versatiledb we were using
was pre-v7.
We could have moved to -M vexpress-*, but in the end decided to go for
-M virt due to its simpliciy, and uniformity with aarch64.
platform_device: does not work anymore and was removed, since it was tied
to versatilepb.
We left a mention on the README and removed all in tree source. The QEMU
patch is still left as it was.
As a consequence, the linux tree had no other patches, and we now use
vanilla linux by default, which is a great thing for reproducibility.
Another consequence is the /poweroff.out works for arm -M virt,
and we removed all mentions of the problem.

Otherwise, on the git module update fallback, QEMU's submodules don't get updated.
Also add a --recursive to the main qemu clone, just in case they add
submodules to the submodules in the future.
