nvmemon: libzpci: Skip SCLP on NVMes with non-IBM subsystem vendor ID

Browse Source 
The SCLP Write Event Data Action Qualifier 4 is only available for
NVMes with subsystem vendor ID matching IBM. Add both IDs to struct
zpci_dev in libzpci. Also add them to the libzpci_example output
and adjust its output to multiline to handle more data.
