Because qtest does not support s390 channel I/O, s390 only performs smoke tests on
those few devices that do not have any functional tests. Therefore, every time we
add functional tests for a virtio device, the choice is between removing
those tests from the s390 suite (so that s390 actually _loses_ coverage)
or sprinkling the test with architecture checks.
This patch simply creates a ccw-specific test that only performs smoke tests on
all virtio-ccw devices. If channel I/O support is ever added to qtest and libqos,
then this file can go away. In the meanwhile, it simplifies maintenance and
makes sure that all virtio devices are tested.

The "max" CPU model behaves like "-cpu host" when KVM is enabled, and like
a CPU with the maximum possible feature set when TCG is enabled.
While the "host" model can not be used under TCG ("kvm_required"), the
"max" model can and "Enables all features supported by the accelerator in
the current host".
So we can treat "host" just as a special case of "max" (like x86 does).
It differs to the "qemu" CPU model under TCG such that compatibility
handling will not be performed and that some experimental CPU features
not yet part of the "qemu" model might be indicated.
These are right now under TCG (see "qemu_MAX"):
- stfle53
- msa5-base
- zpci
This will result right now in the following warning when starting QEMU TCG
with the "max" model:
"qemu-system-s390x: warning: 'msa5-base' requires 'kimd-sha-512'."
The "qemu" model (used as default in QEMU under TCG) will continue to
work without such warnings. The "max" model in the current form
might be interesting for kvm-unit-tests (where we would e.g. now also
test "msa5-base").
The "max" model is neither static nor migration safe (like the "host"
model). It is independent of the machine but dependends on the accelerator.
It can be used to detect the maximum CPU model also under TCG from upper
layers without having to care about CPU model names for CPU model
expansion.

The PL08x model currently will unconditionally call hw_error()
if the DMA engine is enabled by the guest. This has been
present since the PL080 model was edded in 2006, and is
presumably either unintentional debug code left enabled,
or a guard against untested DMA engine code being used.

Currently our PL080/PL081 model uses a combination of the CPU's
address space (via cpu_physical_memory_{read,write}()) and the
system address space for performing DMA accesses.
For the PL081s in the MPS FPGA images, their DMA accesses
must go via Master Security Controllers. Switch the
PL080/PL081 model to take a MemoryRegion property which
defines its downstream for making DMA accesses.
Since the PL08x are only used in two board models, we
make provision of the 'downstream' link mandatory and convert
both users at once, rather than having it be optional with
a default to the system address space.
