[PATCH v2 0/3] s390x: improve documentation

[Cornelia Huck]

The documentation for the s390x system emulation target still has quite
a bit of room for improvement, so I started adding some device documentation.

v1->v2:
- css.rst: added example for cssid == 0 (Thomas)
- css.rst: mention what the properties look like (Thomas)
- css.rst: it's "channel subsystem image" (me)
- 3270.rst: make introduction less confusing (Thomas)
- 3270.rst: fix device name (Thomas)
- 3270.rst: use unprivileged port (Thomas)
- vfio-ccw.rst: add mdevctl example (Thomas)
- vfio-ccw.rst: formatting tweaks (Thomas)

Cornelia Huck (3):
  docs/s390x: document the virtual css
  docs/s390x: document 3270
  docs/s390x: document vfio-ccw
