af210a7671 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.

3fdabbda61 configure: updated submodules recursively 
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.
