By using the sysbus interface it is possible to wire up the esp/le devices
to the sun4m DMA controller directly during sun4m_hw_init() instead of
passing qemu_irqs into the sparc32_dma_init() function.
This is an intermediate step to allow further reorganisation as more logic
is moved into the relevant SPARC32 DMA devices; there will be a final
refactoring of sparc32_dma_init() once this work is complete.

Due to slight differences in behaviour accessing the registers for the
esp and le devices, create two separate SPARC32_DMA_DEVICE types and
update the sun4m machine to use.
Note that by using different device types we already know the size of
the register block and the value of is_ledma at init time, allowing us to
drop the SPARC32_DMA_DEVICE realize function and the is_ledma device
property.

Starting a guest with
<os>
<type arch='s390x' machine='s390-ccw-virtio-2.9'>hvm</type>
</os>
<cpu mode='host-model'/>
on an IBM z14 results in
"qemu-system-s390x: Some features requested in the CPU model are not
available in the configuration: gs"
This is because guarded storage is fenced for compat machines that did
not have guarded storage support. While this prevents future migration
abort (by not starting the guest at all), not being able to start a
"host-model" guest is very much unexpected. As it turns out, even if we
would modify libvirt to not expand the cpu model to contain "gs" for
compat machines, it cannot guarantee that a migration will succeed. For
example if the kernel changes its features (or the user has nested=1 on
one host but not on the other) the migration will fail nevertheless. So
instead of fencing "gs" for machines <= 2.9 lets allow it for all
machine types that support the CPU model. This will make "host-model"
runnable all the time, while relying on the CPU model to reject invalid
migration attempts. We also need to change the migration for guarded
storage.
Additional discussions about host-model are still pending but are out
of scope of this patch.

It 'works' with default CPU only because of bug in
moxie_cpu_class_by_name() where it treats cpu_model
as type name and default cpu_model also happens to be
type name. But specifying explicitly cpu on CLI,
ex: '-cpu MoxieLite', makes QEMU fail since
moxie_cpu_class_by_name() doesn't traslate cpu_model
to cpu type and fails to find corresponding object class.
Fix moxie_cpu_class_by_name() to do proper
cpu_model -> cpu type
translation and fix default cpu_model to be cpu_model
instead of being typename.

Trying to call xengnttab_set_max_grants() with the same file handle
might fail on some kernels, as this operation is allowed only once.
This is a problem for the qdisk backend as blk_connect() can be
called multiple times for a domain, e.g. in case grub-xen is being
used to boot it.
So instead of letting the generic backend code open the gnttab device
do it in blk_connect() and close it again in blk_disconnect.

The Xen qdisk backend needs to test whether grant copy operations is
available in the kernel. Unfortunately this collides with using
xengnttab_set_max_grants() on some kernels as this operation has to
be the first one after opening the gnttab device.
In order to solve this problem test for the availability of grant copy
in xen_be_init() opening the gnttab device just for that purpose and
closing it again afterwards. Advertise the availability via a global
flag and use that flag in the qdisk backend.
