sysbus: Remove ignored return value of FindSysbusDeviceFunc
Functions of type FindSysbusDeviceFunc currently return an integer. However, this return value is always ignored by the caller in find_sysbus_device(). This changes the function type to return void, to avoid confusion over the function semantics.
