macio: move OpenPIC inside macio-newworld device

The OpenPIC device is located within the macio device on real hardware so make it
a child of the macio-newworld device. This also removes the need for setting and
checking a separate PIC object property link on the macio-newworld device which
currently causes the automated QOM introspection tests to fail.
