s390/cio: Add new Operation Code OC3 to PNSO
Add support for operation code 3 (OC3) of the Perform-Network-Subchannel-Operations (PNSO) function of the Channel-Subsystem-Call (CHSC) instruction. PNSO provides 2 operation codes: OC0 - BRIDGE_INFO OC3 - ADDR_INFO (new) Extend the function calls to *pnso* to pass the OC and add new response code 0108. Support for OC3 is indicated by a flag in the css_general_characteristics.
