  Add a Device Tree binding schema for the OLED panels based on the
Solomon SSD133x family of controllers.

Changes in v3:
- Move solomon,ssd-common.yaml ref before the properties section and
  width/height constraints after the other properties (Conor Dooley).

Changes in v2:
- Unconditionally set the width and height constraints (Conor Dooley).
- Fix indentation in the DTS examples (Krzysztof Kozlowski).
