sysbus: make SysBusDeviceClass::init optional 



Make the SysBusDeviceClass::init optional, for devices which
genuinely don't need to do anything here. In particular, simple
devices which can do all their initialization in their
instance_init method don't need either a DeviceClass::realize
or SysBusDeviceClass::init method.
