KVM: s390: Enable guest EDAT2 support
1. Enable EDAT2 in the list of KVM facilities
2. Handle 2G frames in pfmf instruction
If we support EDAT2, we may enable handling of 2G frames if not in 24
bit mode.
3. Enable EDAT2 in sie_block
If the EDAT2 facility is available we enable GED2 mode control in the
sie_block.
