This patch introduces a new diag288 watchdog device that will, just like
other watchdogs, monitor a guest and take corresponding actions when it
detects that the guest is not responding.
diag288 is s390x specific. The wiring to s390x KVM will be done in
separate patches.

[split out qemu-option.hx base changes]
pci.mak includes a lot of devices - and most of them do not make
sense on s390x, like USB controllers or audio cards. These devices
also show up when running "qemu-system-s390x -device help" and thus
could raise the hope for the users that they could use these kind
of devices with qemu-system-s390x. To avoid this confusion, we
should not include pci.mak and rather include the bare minimum
manually instead.

This patch implements a pci bus for s390x together with infrastructure
to generate and handle hotplug events, to configure/unconfigure via
sclp instruction, to do iommu translations and provide s390 support for
MSI/MSI-X notification processing.

Introduce a common parent class for both cases, where kvm and non-kvm
can hook up callbacks. This will be used by follow-on patches for
adapter registration and mapping.
We now always have a flic, regardless of whether we use kvm; the
non-kvm implementation just doesn't do anything.

Make virtio devices optional. Selecting individual devices is not useful
as the host bindings are all in one file.
