As I understand it, these devices are actually directly connected to the
IPSS. However, for such a topology to work correctly, we'll probably need
some changes in the hwmod core. I had hoped to have this done for 3.6,
but that's looking pretty unlikely. So instead, will drop some comments
in the data to note that this will need to be fixed.
