Matthew Rosato c68468ed34 s390/pci: stash associated GISA designation ...

For passthrough devices, we will need to know the GISA designation of the
guest if interpretation facilities are to be used.  Setup to stash this in
the zdev and set a default of 0 (no GISA designation) for now; a subsequent
patch will set a valid GISA designation for passthrough devices.
Also, extend mpcific routines to specify this stashed designation as part
of the mpcific command.
