spapr: Remove unnecessary instance_size specifications from DRC subtypes
All the DRC subtypes explicitly list instance_size in TypeInfo (all as sizeof(sPAPRDRConnector). This isn't necessary, since if it's not listed it will be derived from the parent type. Worse, this is dangerous, because if a subtype is changed in future to have a larger structure, then subtypes of that subtype also need to have instance_size changed, or it will lead to hard to track memory corruption bugs.
