I don't think that PPP interface-as-device is very interesting, and it
sort of breaks the model of physical devices in HAL.  Those PPP
properties should probably be merged onto the PDA device itself.

We can probably use a property to describe the communication interface
between the PDA and the system rather than a parent-child relationship.
PDAs are so diverse in this respect we'll need it anyway.
