Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20180504' into staging

First s390x pull request for 2.13.
- new machine type
- extend SCLP event masks
- support configuration of consoles via -serial
- firmware improvements: non-sequential entries in boot menu, support
  for indirect loading via .INS files in s390-netboot
- bugfixes and cleanups
