* getPCIdevice is the whole purpose for this object. This method allows
* callers to get the PCI config address of the PCI device associated
* with this device description. If all goes well, the three params are
* filled in and IO_R_SUCCESS is returned. There are a variety of reasons
* that the address couldn't be known, in which case an appropriate code is
* returned and the parameters are left untouched. It is acceptable for any
* of the parameter pointers to be NULL.
