net/smc: manage system EID in SMC stack instead of ISM driver
The System EID (SEID) is an internal EID that is used by the SMCv2 software stack that has a predefined and constant value representing the s390 physical machine that the OS is executing on. So it should be managed by SMC stack instead of ISM driver and be consistent for all ISMv2 device (including virtual ISM devices) on s390 architecture.
