ppc/pnv: Make PnvXScomInterface an incomplete type

Browse Source 
PnvXScomInterface is an interface instance. It should never be
dereferenced. Drop the dummy type definition for extra safety,
which is the common practice with QOM interfaces.

While here also convert the bogus OBJECT_CHECK() to INTERFACE_CHECK().
