s390x/cpumodel: add zpci, aen and ais facilities
zPCI instructions and facilities are available since IBM zEnterprise EC12. To support z/PCI in QEMU we enable zpci, aen and ais facilities starting with zEC12 GA1. And we always set zpci and aen bits in max cpu model. Later they might be switched off due to applied real cpu model. For ais bit, we only provide it in the full cpu model beginning with zEC12 and defer its enablement in the default cpu model to a later point in time. At the same time, disable them for 2.9 and older machines. Because of introducing AIS facility, we could check if it's enabled to initialize flic->ais_supported with the real value.
