Auger Eric April 28, 2015, 4:51 p.m. UTC 
Add a new callback in the SysBusDeviceClass. This callback now can
be overriden by devices inheriting from sysbus. By default the callback
is set to the dummy object_property_allow_set_link callback.

Signed-off-by: Eric Auger <eric.auger@linaro.org>

---

v1 -> v2:
- use new LinkPropertySetter type
